In 2002, Cingular Wireless introduced Rollover minutes. Instead of losing unused minutes, they simply rolled over to the next month. On December 31st, they vanished and you started all over. Today, rollover minutes are useless as all carriers now offer Unlimited voice calling plans. T-Mobile's approach of offering free Music Streaming, FREE Video Streaming and should you use all of your 4G data, throttling, makes it very difficult to use all of your 4G data.
By offering free texting and unlimited data in 140 countries, T-Mobile offers the best global footprint of all US carriers. If that wasn't awesome enough, unlike the other carriers, T-Mobile only charges $0.20 per minute global voice roaming fees while in these 140 countries.
