What drives mobile telephony adoption in Rural India? Anempirical evaluation.
ABSTRACT
Mobile telephony has become one of the major factors driving the social and economic
development of a country. It has diffused differently in diverse economies with different factors
affecting the process. Mobile telephony has penetrated markets throughout India. The ratio of
mobile penetration in urban to rural India is 4:1 which clearly indicates that different social
systems adopt the same technology in different ways. An understanding of the factors affecting
the choice is essential both for economists studying the determinants of growth and for the
providers of such technologies. Whilst most of current studies on mobile telephony are based onurban users, this paper focuses on users living in rural India. The objective of this paper is to
understand and identify factors for adoption of mobile telephony in rural India and their impact
on its adoption.
This study employs a mixed approach to examine the factors affecting the intention to adopt
mobile telephony in rural India. The results highlight that mobility, social influence, perceived
usefulness, cost of handset, lack of ease of service accessibility and lack of understanding of
mobile service offerings are the key factors affecting the rural people decision to adopt mobile
telephony. This study is useful for researchers willing to highlight the factors that motivate users
mobile telephony adoption in rural India. It also has implications for government and service
providers seeking to enhance its adoption in India. For practitioners, our findings suggest that in
order to facilitate adoption of mobile telephony and its related services, it is crucial to strengthen
user perception on the potential benefits and to create transparency of the services.

INTRODUCTION
In recent years, there is increasing evidence from both academic researchers and policymakers
that the use of mobile telephony is the important base for economic growth and social
development of a country. Studies at country level have shown that wireless phones have a
positive and significant impact on economic growth (Waverman, Meschi, & Fuss, 2005). A
study by Abraham (2007) found that the widespread use of mobile telephony by Kerala
fishermen has increased the efficiency of markets by decreasing risk and uncertainty. But
adopting a technology is a complex process and involves a mix of social, technological,
economical and political factors influencing its adoption decision. Even though the growth of
mobile telephony is a global story, there are important regional differences in how the mobile
telephony has evolved and diffused in different countries. Indian Telecom sector has undergone amajor transformation during recent years and is now the second-largest telecom market, just after
china. Figure 1 presents the penetration of mobile telephony in India since 1997. The ratio of
mobile penetration in urban to rural India is 4:1. Also, the urban to rural subscribers are in the
ratio of 2:1. These numbers indicates that different social systems adopt the same technology in
different ways.

A deeper insight is required to understand the underlying motivations that lead to
adoption of mobile telephony in rural India. While most of current studies on mobile telephony
are based on urban users, this paper focuses on users living in rural India. The objective of this
paper is to understand and identify factors for adoption of mobile telephony in rural India and
their impact on adoption. Our findings will provide valuable managerial insights for service
providers and policymakers. The mixed approach is adopted in this study as a research
methodology. The study was conducted in two phases (phase 1 being qualitative and phase 2
being quantitative)
LITERATURE REVIEW ON ADOPTION AND DIFFUSION APPROACH
Adoption relates to consumers individual decision making process with regard to the purchase
and use of new products and services. Diffusion equals the sum of consumer adoptions in a
market over time (Gatignon & Robertson, 1985). Studies on diffusion describe and predict the
cumulative response of consumers to a new technology/product/service in a market. Thus,
research on adoption is directly linked to research on diffusion. Also Gatignon and Robertson
(1985) stated that: adoption lies at the heart of diffusion. The literature on adoption and diffusion
includes two major streams: econometric models and explanatory models. Econometric
approaches study epidemic models, which describe the phenomenon at country level. Gatignonand Robertson's (1985) consumer diffusion paradigm is an example of an explanatory model
which links individual characteristics and experience to adopt an innovation. The research about
adoption decision mainly studies the factors influencing individual adoption from the angle of
individual. Such research from individual perspective compensates the lack of study from overall
angle, and considers individual heterogeneity. There are various theories relating to the adoption
of new services or technologies that exist in the literature such as innovation diffusion
theory/DOI (Rogers, 1962), theory of reasoned action/TRA (Ajzen & Fishbein, 1977), theory of
planned behavior/TBP (Ajzen, 1991) and technology acceptance model TAM (Davis, 1989).
DOI theory suggests that an individuals adoption decision is influenced by the five
perceived characteristics of innovation - relative advantage, complexity, compatibility,
trialability, and observability. Moore and Benbasat (1991) have expanded DOI theory and
suggested seven innovation characteristics (relative advantage, ease of use, compatibility, image,

visibility, result demonstrability and trialability) that influence the adoption decision. Davis
(1989) has proposed a model that provides an explanation toward the acceptance of technology
which explains users behavior on accepting new information technology and analyzes the
factors that influence their intention toward its adoption. This model is popularly known as
Technology Acceptance Model (TAM) and contained three factors affecting behavioral intention
(IA) to adopt: (1) Perceived ease of use (2) Perceived Usefulness (3) Attitude. TAM has been
highly praised for its parsimony and predictive power (Mathieson, 1991) which makes it easy to
apply to different situations. The model has been continuously studied, modified and expanded
by researchers. Davis , Bagozzi and warshaw (1989) used the original TAM model and found
strong and significant correlation between PU, PEOU and intention to use the system thus
eliminating the need for the attitude construct from the model. This can be explained in that if a
system is perceived to be useful, people may have a high behavioral intention to adopt eventhough they do not have a positive attitude toward it (Davis et al., 1989). The resultant model is
presented in Figure 2. Venkatesh and Davis (1996) also removed attitude from their revised
model because attitude did not appear to mediate fully the effect of perceived usefulness and
perceived ease of use on behavioral intention as originally anticipated.
Figure 2: TAM (Source: Davis, Bagozzi and Warshaw (1989))
The widely followed Davis and Rogers models are complementary. Specifically,
usefulness and ease of use in Davis model is similar to relative advantage and complexity in
Rogers model respectively. Constructs employed in TAM are fundamentally a subset of the
perceived innovation characteristics and, if integrated, could provide an effective model than

either standing alone. The TAM has been used in various information and communication
technology adoption studies like V-mail and customer dial up system (Subramanian, 1994),
spreadsheet and word processor (Jackson, Chow & Leitch, 1997), world wide web (Lederer,
Maupin, Sena & Zhuang, 2000), internet banking (Suh & Han, 2002), wireless internet (Lu , Yu,
Chang & Yao, 2003) .
Only recently the TAM is being applied to mobile services in urban environment of
developed nations. Kuo and Yen (2008) applied TAM to understand the intention to use 3G
value added services in Taiwan. The study of advanced mobile services was done by Lpez-
Nicols (2008) to assess its acceptance by Dutch consumers. It was found that traditional
antecedents of behavioral intention, ease of use and perceived usefulness, can be linked to
variables, such as social influence and perceived benefits. Kim and Garrison (2009) extended the
TAM model to investigate the mobile wireless technology adoption in Korea. Yongqing,Jinlong, Jianhua, and Yuanyuan (2011) also extended the model to understand the adoption of
mobile instant messaging in china.
The studies have shown strong empirical findings which have encouraged the models
use in our study. A key research opportunity emerges to apply and extend these models in rural
context of developing nation, in our case India for investigating the adoption and diffusion of
mobile telephony. Pursuing this would address the theoretical gap highlighted in sections above
and will offer a fresh theoretical perspective for explaining mobile telephony adoption in rural
India, a developing nation. Further, these factors that shape ones intentions will also help
service providers to leverage optimally and control those factors in order to promote adoption
and diffusion. And, therefore the first logical step is to understand and find how and why users
adopt mobile telephony in rural India.
CONCEPTUAL MODEL AND HYPOTHESIS
Phase 1 of the study was conducted to find new factors in Indian rural context and to come up
with a conceptual model. Open ended questions were asked to the owners and users of mobile
telephony (basic voice service). The data collected helped to give a broad picture of users
perception and provided new insights. Most of the factors explored were in line with those
concluded from literatures. Perceived health hazard, lack of service quality, lack of ease of

service accessibility, cost of service, cost of handset and lack of understanding of mobile service
offerings came out as new factors. Direct and indirect linkages between variables were also
identified.
Figure 3. Conceptual Model
Based on the literature review and phase 1 of the study conceptual model for adoption of mobile
telephony in rural India is proposed as shown in Figure 3. To study at end user level, Intention to
Adopt (IA) is used as the dependent variable. IA is defined as the strength of the adopters
intention to support the adoption decision (Ajzen & Fishbein, 1977). The operational definition
and description of the variables identified and there hypothesis are described as under
Perceived usefulness (PU)is defined as the degree to which a person believes that using
mobile telephony would enhance his or her personal communication performance or
effectiveness (Davis 1989). Prior research has found that perceived usefulness is the strongest

predictor of intention to adopt (Venkatesh, Morris & Davis, 2003). The relation between
usefulness and adoption intention was also confirmed by Lopez-Nicoas (2008) for advanced
mobile service in Netherlands. Phase 1 of our study also supported the persistence of its
influence in the current context. Perceived ease of use (PEOU)is defined the degree to which a
person believes that using mobile telephony would be free of effort (Davis, 1989). It has also
been found to be an important factor for various technologies (Davis, Bagozzi & Warshaw
1989). In addition, perceived ease of use has been found to indirectly influence intention through
perceived usefulness (Davis et al. 1989). PEOU has shown a significant effect on PU in the
majority of studies but the effect of PEOU on intention has shown inconsistent results. In the
study of Kuo and Yen (2009), ease of use was found to have an indirect effect on intention to
adopt 3G service. Relationship of perceived ease of use on adoption intention was confirmed by
Kim and Garrison (2008) for mobile wireless technology in Korea. Therefore, the hypothesis isH1: PU has a positive effect on intention to adopt mobile telephony in rural India.
H2a: PEOU has a positive effect on intention to adopt mobile telephony in rural India.
H2b: PEOU has a positive effect on perceived usefulness.
Previous researchers have studied the diffusion of technology with respect to culture and
have found that in individualistic culture diffusion of technology happens at a faster rate. Highly
individualistic cultures are those in which individual is the most important unit, while highly
collectivistic cultures believe that the group is the most important unit. In collectivistic
environment one act conforms the norms of the group. As collectivistic cultures are characterized
by collective decisions, it results in delay in the adoption decision process. Because collective
culture emphasize on conformity to social norms and group behavior, the adopters of technology
in this culture will be socially influenced while making any adoption decision (Yaveroglu &
Donthu ,2002; Bulte & Stremersch,2004). On similar grounds, the culture in metropolitan cities
and urban India can be considered to have less collective culture as compared to rural India. This
can be one of the reasons of slow diffusion of mobile telephony in rural area. It also lays
importance of social influence (SI) in the context of the study (rural India). In the current context
social influence is defined as the degree to which individuals believed that others thought they
should adopt mobile telephony. On the other side, mass media (MM) influence is defined as the
degree to which people had the impression that mass media reports encouraged them to adopt
mobile telephony. Social influence is generally interdependent with mass media and seems to
-

be more important in the earlier phases of adoption, rather than late. However when conflict
occurs, social influence is found to have a greater impact (Gatignon and Robertson's, 1985). It is
because, opinions and pressures from the peer group reduces the perceived risk associated with
adoption. Potential users may feel that adopting mobile telephony does not require much effort
and is useful if others in their social surroundings say that the system is easy to use. Thus
individuals beliefs are socially framed through interactions with other members and it will have
significant impact on the individual perceived usefulness and perceived ease of use over the
characteristics of mobile telephony.
In Innovation diffusion theory image is also included as an important aspect of relative
advantage. Personal Image is defined as the degree to which use of an innovation is perceived
to enhance ones image or status in ones social system. Research of Van den Bulte and
Stremersch (2004) indicates that the competition for status is an important growth driver,sometimes more important than interpersonal ties, and that the speed of diffusion increases in
societies that are more sensitive to status differences. In some parts of rural India, adopting a
mobile telephony is still a luxury. When an individual adopts a mobile telephony, his or her
relationship to their immediate social context is considerably transformed and raised. Users
perceive that they have entered the modern and urban spheres. They regard it as fashion and
decide to adopt it to symbolize their social progress. It is also believed that social influence will
affect image because if important members in an individuals social group believe that a person
should have mobile telephony then adopting it will raise the standing of the individual within the
group. Hence based on the above discussion, the hypothesis is
H3a: MM has a positive effect on intention to adopt mobile telephony in rural India
H3b: MM has a positive effect on SI.
H4a: SI has a positive effect on intention to adopt mobile telephony in rural India.
H4b: SI has a positive effect on PU.
H4c: SI has a positive effect on PEOU.
H4d: SI has a positive effect on PI.
H4e: SI has a positive effect on mobility.
H5a: PI has a positive effect on intention to adopt mobile telephony in rural India.
H5b: PI has a positive effect on PU.

Mobility is perceived to be the most significant feature of mobile telephony. Mobility
(MOB) is defined as the degree to which one can use the innovation anytime and anywhere.
Dholakia and Kshetri (2004)found mobility refereeing to anytime, anywhere capability to be
one of the factor influencing the diffusion of mobile telephony. Looney, Jessup and Valacich
(2004) stated that the capability of communicating from virtually anywhere at any time offers
convenience which can influence adoption intention. Therefore, the hypothesis is
H6a: MOB has a positive effect on intention to adopt mobile telephony in rural India.
H6b: MOB has a positive effect on perceived usefulness.
People in India are price sensitive and avoid over expenditure, the other influencing
factor is the technology cost. Technology cost includes two aspects: the running cost which is
defined as the cost of service (mobile call charges (CS)) and the onetime cost defined as the cost
of the handset (CH). A mobile call was priced at rupee 16 per minute in 1994, it is now aboutrupee 0.50 per minute. A STD calls was priced at rupee 36 per minute in 1994, today it is rupee
0.40 per minute. The mobile handset was costing over Rs. 8000 in 1994. It is now about less than
Rs. 1500 (Chowdhary, 2006). These innovations are providing relative advantage to the users
which they assess while adopting the mobile telephony. As over expenditure and loans are not
encouraged among Indian society especially in rural India, we believe that technology cost can
act as barrier towards adoption decision, thus delaying the diffusion process. Therefore, the
hypothesis is
H7a: CS has a negative effect on intention to adopt mobile telephony in rural India.
H7b: CS has a negative effect on perceived usefulness.
H8a: CH has a negative effect on intention to adopt mobile telephony in rural India.
H8b: CH has a negative effect on perceived usefulness.
One of the limitations of TAM is that it assumes that the service is accessible. We believe
that constrained access influences the perceptions of potential adopters about the mobile
telephonys true usefulness and hence the adoption decision resulting in slow diffusion in rural
India. Explored in Phase 1of the study, ease of service accessibility (EOSA) is defined as the
degree to which product, service or related environment is easily available to get benefit from
the service. More than 90% of Indian mobile subscribers hold prepaid account and recharge
through prepaid coupons. In the prepaid account the subscriber has the direct control /
monitoring of his expenditure and can regulate his expenditure limits with respect to priorities.

Also consumer is free of doubts related to bills as he is continuously informed and updated about
his expenditure. Lack of easy access of mobile innovations- like prepaid calling cards and low
cost handset in the area and availability of electricity for recharging handset can act as external
controls and hindrance in the adoption environment leading to retardation of diffusion of mobile
telephony. Therefore, the hypothesis is
H9a: Lack of ease of service accessibility (LEOSA) has a negative effect on intention to adopt
mobile telephony in rural India.
H9b: LEOSA has a negative effect on perceived usefulness.
During phase 1 of the study, the factor perceived health hazard was explored. PHH is
defined as an unknown and unpredictable phenomenon that adversely affects ones health. It
can be an important barrier in the diffusion of mobile telephony in rural India. In the study of
Cocosila Turel, Archer and Yuan (2007) in Canada, health hazard was found to have smallnegative indirect influence on the intention to adopt 3G cell phones. It had a diminishing effect
on PU. The main conclusion drawn from their analysis was that PHH perceptions affect the PU
of 3G cell phones, which in turn influences user IA. Therefore, the hypothesis is
H10a: PHH has a negative effect on intention to adopt mobile telephony in rural India.
H10b: PHH has a negative effect on PU.
Service quality (SQ) is defined as the extent to which a service meets the users
requirements or expectation. In this study ease of subscribing, customer support
(responsiveness) and network (coverage aspect) are taken as three dimensions of service quality
as examined during phase 1 of the study. Based on the previous literature, the hypothesis can be
stated as:
H11a: Lack of SQ (LSQ) has a negative effect on intention to adopt mobile telephony in rural
India.
H11b: LSQ has a negative effect on PU.
H11c: LSQ has a negative effect on PEOU.
During phase 1 of the study, the factor understanding of mobile service offering
(UMSO) was explored. It is defined as ones ability to clearly visualize the mobile telephony
benefits in thought and understanding. It relates to the transparency of the services that are on
offer and the ease of being able to differentiate between these services. Thus the hypothesis can
be stated as:
-

H12a: Lack of UMSO (LUMSO) has a negative effect on intention to adopt mobile telephony in
rural India.
H12b: LUMSO has a negative effect on PU.
H12c: LUMSO has a negative effect on PEOU.
RESEARCH DESIGN
The methodology used is both qualitative and quantitative, the mixed methodology. Phase 1 of
the study was qualitative in nature to find new factors in Indian context and to derive the
conceptual model. Phase 2 of the research is quantitative in nature to find factors that affect
adoption in rural India. This combination of qualitative and quantitative approaches helped to
ensure the sufficiency and quality of obtained evidence.
Based on the conceptual model presented in Figure 3, the survey instrumentaquestionnairewas developed to measure the effect of factors that were thought to influence an
intention to adopt mobile telephony. All the items were measured on five point likert scale.
Questionnaire was given to some of the experts in the field to assess the face validity to eliminate
ambiguity in questions. Modifications were made accordingly without affecting the intended
meanings. Prior to the main study, a pilot test using 20 people (age range from 18-45) from the
rural area of India was conducted to validate the relevance, accuracy and wording of content of
the questionnaire. Reliability of measures was assessed through Cronbach Alpha. It shows that
that all alpha value exceeds or nearly meets the minimum of 0.6 (Hair, Black, Babin, Anderson
and Tatham, 2006). The questionnaire had undergone 2 revisions before the main study and then
was distributed in Hindi as it was the language understood by 95% of the people in the area.
Initially people willing to participate were asked whether they had any experience with mobile
telephony. Final questionnaire was distributed amongst 180 people in the rural state of India-
Chhattisgarh. Rationale for selecting the state was the increasing growth rate of subscribers and
low mobile density. Also, the state is primarily a rural state with only 20% of population
residing in urban areas. 170 responded back and only 148 were found usable.

The data used was collected in the November 2010 from rural part of the Indian state
Chhattisgarh. Table 1 presents the characteristics of the sample. Out of 148 respondents, 141
were prepaid users. 59% of the users were the subscribers (owners of subscriber identity module
(SIM)). 55 % of the respondents have less than 3 years of experience in using mobile. It was
found that only 21% of the household have fixed line telephony. The mean age of the
respondents was 23 years and mean of the experience of the respondents with mobile telephony
was 2.8 years.

came out as 0.60. Indicators which have loadings below 0.5 were removed and then again
exploratory factor analysis was performed. The measurement model was then tested by
performing validity and reliability analyses on each of the items of the model, in order to ensure
that only reliable and valid items of the constructs are used before conclusions about the nature
of the relationships between construct are drawn. Table 2 presents the reliability measures of the
factors. Model is also evaluated using three criteria suggested by Fornell and Larcker (1981).
Table 2 shows that construct reliabilities exceed and average variance extracted (AVE) of each
construct exceed 0.7 and 0.5 respectively. Indicator factor loading are significant and exceed 0.5
(Table 3). Table 4 shows that square root of the constructs AVE is greater than the correlation of
the other constructs. The construct PHH was removed from the further analysis due to low
cronbach alpha. Reliability of formative constructs (lack of service quality, lack of ease of
service accessibility) was checked by testing the significance of the weights and the measureswith significant weights were only considered for the analysis.

Hypothesis Testing
Conceptual model was tested using Partial Least Squares (PLS), a structural modeling technique
well suited for complex models using software smartPLS. This technique allowed for the
understanding of the relationship between the constructs and was considered appropriate for thisstudy due to its to handle smaller sample sizes and use of less strict distributional assumptions
(Gyau and Spiller, 2009; Ringle et al 2005). A rule of thumb for robust PLS path modeling
estimations suggests that the sample size should be equal to the larger of the following (Barclay,
Higgins, and Thompson, 1995): (1) ten times the number of indicators of the scale with the
largest number of formative indicators, or (2) ten times the largest number of structural paths
directed at a particular construct in the inner path model. Based on these necessities, our model
meets the sample size requirement. The model was able to explain 35 % of variance in intention
to adopt mobile telephony in the rural state of India. Currently available PLS software does not
automatically provide goodness-of-fit measures for the full path model. However, a method to
calculate an overall goodness-of-fit (GoF) measure was proposed by Amato , Esposito and
Tenenhaus (2004). GoF was found to be 0.24 suggesting a moderate fit of the model. Chin
(1998) suggests that path coefficients should exceed 0.1 - 0.2. In this model we see that majority
of path coefficients exceed the lower 0.1 level suggesting that the model adequately fits the data.
A further test of model fit is provided by Chin (1998) who suggests that R square of 0.66
indicates substantial model fit, R square 0.35 moderate and R square 0.17 weak model fit. Usingthese criteria it appears that this model fits the data moderately well with R square of 0.35.
Bootstrap analysis was performed to test the statistical significance of path coefficients. Path
coefficients represent the strength of the relationships between dependent and independent
variables and are presented in figure 4. It is found that PU, MOB, CH, LEOSA and LUMSO are
the factors directly affecting the adoption intention and hence are the responsible factors for the
diffusion of mobile telephony in Chhattisgarh. To study how (or the mechanism by which) a
given effect occurs between an independent variable and a dependent variable, mediation effect
is analyzed. Some of the variables are indirectly related to the adoption intention. The effect of
SI on IA is mediated by PU, PEOU, MOB and PI. Also the effect of CH, CS, LEOSA, LSQ and
LUMSO on IA is mediated by PU. To assess these mediation effects Sobel test is performed
(Sobel, 1982). To find the mediating effect of PU on relationship between SI and IA sobel tests
was performed by considering the total effect (i.e., the sum of the direct and indirect effects) of
-

RESULTS AND DISCUSSION
Based on the qualitative analysis six new factors have been identified affecting the intention to
adopt mobile telephony in rural India. These six factors are perceived health hazard, lack of
service quality, lack of ease of service accessibility, cost of service, cost of handset and lack ofunderstanding of mobile service offerings. A conceptual model was developed incorporating
these factors and was validated and tested. The quantitative analysis has shown that the proposed
factors significantly influence users' intention to adopt mobile telephony.
Results indicate that mobility, perceived usefulness, lack of ease of service accessibility
and lack of understanding of mobile service offerings are the direct antecedents of adoption
intention in rural India. Mobility was found to have highest effect, followed by perceived
usefulness and lack of service quality respectively.
The results of our study indicate that social influence exerts an important influence on
peoples decision to adopt mobile telephony in rural India. The opinions of friends and relatives
have a significant impact. Participants expressed that their awareness of mobile telephony and
related service came from mass media, such as advertisements on television, newspaper, radio
but they rarely consider them as direct influence sources on their adoption making decision.
Users mostly consider them as information sources, and were mainly convinced after the
opinions of their friends and relatives. The findings are in line with the literature.
The finding of positive relation between the lack of ease of service accessibility andintention to adopt is in contrast to the common belief of negative relationship between the two.
This state is due to the users (adopters and potential adopters) having high degree of perceived
usefulness (benefits) and is rushing for adoption in spite of the lack of service accessibility. The
delay in mobile telephony adoption and getting its benefits is not appreciated by the users. This
state may represent a case where demand exceeds the supply. The demand generates shortage of
services resulting into competition among adopters to adopt ahead of others even with
difficulties and partial availability of service and its product. The diffusion of usefulness has
generated a demand to an extent that even the partial service and difficulties in getting them are
being tolerated and ignored by the users (adopters and potential adopters). This shows that
improving and simplifying the mechanisms by which end-users access mobile telephony could
be key to enhance its adoption and usage in the region. Increased access is an important step
towards increasing the mobile penetration in rural India.

Relationship between lack of service quality and ease of use came out to be positive. This
positive relationship is in contrasts to the general findings in previous literature. This typical
situation indicates that the adopters are ready to accept the mobile telephony in spite of
increasing difficulties in getting the service. The adopters perceive that they can derive benefits
by using the service without waiting for service quality improvement to take place.
Cost of mobile service was found to be insignificant. One of the reasons could be the low
affordable tariffs due to competition between the service providers. Most of the people in rural
India use the Missed Call concept which reduces their burden of payment for the service. Thus
it can be stated that cost of service may affect their usage levels and but not the adoption
decision. The cost of handset was found to be positively related to usefulness. Few reasons might
explain this situation. First, the majority of the respondents of this study were made up of ruralstudents (who are the potential adopters), who basically rely on either their parents or
sponsorship to survive. Thus, they might not treat money as serious as the general population in
the country. Also students might feel that handset of higher cost will show off the status thus
helping them to create a unique image.
The lack of understanding of mobile service offerings was found to be negatively
impacting adoption and ease of use of mobile telephony thereby making diffusion slow in the
region. The impact is small but significant. The service providers should take into account and
must clearly differentiate between different services and plans and should communicate the
benefits more clearly to the population
IMPLICATIONS FOR RESEAERCH AND PRACTICE
The study contributes to adoption and diffusion research by using detailed primary data in the
rural context of developing nation. This study has extended the body of knowledge with respect
to understand how and why individuals decide to adopt mobile telephony in rural India. We haveextended the technology acceptance model in a completely new environment where the research
is negligible and have integrated the four new variables- lack of ease of service accessibility, cost
of handset, cost of service, lack of understanding of mobile service offerings that affect the
decision to adopt mobile telephony. We believe that our conceptual model is the contribution to

the existing knowledge because it adds unexplored dimensions that influence the adoption and
diffusion in rural context of emerging country.
As a result it will help managers to understand what drives adoption in rural context from
social, economic and psychological perspective. A deeper understanding of factors influencing
the adopters to adopt mobile telephony in rural India can assists service providers in addressing
the right issues and making decision. First of all, our study confirms the critical role of perceived
usefulness in making adoption decision. For practitioners, our findings suggest that in order to
facilitate adoption of mobile telephony and its related services, it is crucial to strengthen user
perception on the usefulness and easy accessibility of services. Significant benefits about the
service should be communicated to the existing and potential adopters. It is found that media has
an indirect effect in adoption decision whereas social influence plays an important role in
adopting mobile telephony directly and indirectly both.The findings indicate that the slow diffusion in rural India is due to its collectivistic
culture. In collectivistic culture one act conforms the norms of the group. As collectivistic
cultures are characterized by collective decisions, it results in delay in the adoption decision
process. Findings suggest that early adopters or opinion leaders, in the local community to which
people in specific area (social network) are attached, should be identified to accelerate the speed
of diffusion.
Managers should take into consideration the significant relationship between these
identified factors and adoption intention while finding the most appropriate strategies for specific
adopters. It will help them to review their current polices and strategies to make their current and
future mobile service more successful. The policy makers and service providers should introduce
training programs related to potential benefits of mobile telephony, and transparency of the
upcoming services and service plans, which can help them to overcome the adoption barriers.
Service providers need to better articulate the potential tangible and intangible benefits that can
be achieved by adopting mobile telephony.
CONCLUSIONS AND LIMITATIONS
The study has developed the model on adoption of mobile telephony in rural India and identified
the factors and their effect on adoption of mobile telephony in rural India. The study was

conducted in two phases and five new factorslack ease of service accessibility, cost of handset,
cost of service, lack of understanding of mobile service offerings and perceived health hazard
were explored. The model establishes the link between the main construct of the TAM i..e PU
and PEOU and the other newly identified variables. The most dominating factors are identified.
They are mobility and usefulness. While this research benefits from rich and focused data
collection on the adoption of mobile telephony, it suffers from few limitations. Majority of the
respondents were in the age group of 25, and this overall profile might limit the generalizability
of research findings. Also the non users of mobile telephony i.e with zero experience were
excluded. The responses of the non users can be significantly different from who responded to
the survey and can give some additional insights. The study on the effect of demographic
variables and experience of the user with mobile telephony on the identified variables is
undergoing.
