The wireless industry has been moving away from all-you-can-eat data plans and toward tiered service plans for the past couple of years. AT&T got the ball rolling on wireless data caps in 2010 when it announced it was dropping unlimited data plans for the iPhone in favor of plans that offered between 200MB and 2GB of data consumption per month. It also began limiting those "unlimited" plans through throttling. Verizon Wireless shortly followed suit by saying it would implement a similar pricing scheme for its 4G LTE services that launched commercially in December 2010, and T-Mobile last year said it would start throttling 3G users down to 2G speeds if they exceeded data consumption caps. Sprint is currently the only mobile carrier that offers users unlimited data plans for smartphones, although the carrier does now impose data caps for devices such as tablets that are likely to use greater amounts of data.
