• Embedded mobile broadband
• Device optimized on a particular use
• User buys the devices from their retail
store at non-subsidized retail prices
• Freedom to purchase a subscription, ad
hoc usage, or a particular service
• The device is the customer
• The carrier subsidizes the device
and manages the supply chain
• Contracts and cancellation
penalties are required to recoup
the subsidy
