39 operators using/planning GSM as an overlay to CDMA network, or as its replacement

A number of CDMA operators are facing falling market share and responding by switching to the GSM family (GSM/EDGE, WCDMA-HSPA) for growth. Some operators choose a dual system strategy, but most prefer to migrate their whole customer base to GSM, the global standard for mobile communications. The vast majority of TDMA operators also chose a migration path to GSM. The case for GSM is compelling, taking into account GSMs unrivalled economies of scale (2.844 billion subscriptions, 86.6% share of the market Q4 2007), feature-rich services, the large number of GSM/WCDMA devices including HSPA, low subscriber acquisition cost, ubiquitous international roaming, and future proof evolution to 3G and beyond, all enabled by 3GPP open-standards EDGE, WCDMA-HSPA, and LTE. UPDATE* February 2008: Several press reports of CAT Telecom (Thailand) plans to migrate from CDMA to GSM
