AT&T;, Sprint and Verizon have joined T-Mobile in eliminating two-year service contracts and phone subsidies for new customers, paving the way for further changes in how consumers pay for their devices.

A December ChangeWave survey of 4,166 respondents took a close-up look at payment options for new devices, along with customer satisfaction, loyalty, and future demand for the major wireless service providers.

The survey also focused on the latest trends in data plans, including T-Mobile’s new Binge On program that allows customers to stream video from select providers without having it count against their data plan. ChangeWave Research is a service of 451 Research.
