T-Mobile is well known for providing very low cost wireless services, the FCC notes. A company with a "history of disruptive competitive conduct," the report describes the firm. "Although T-Mobile faces challenges as the industry develops and responds to the increasing data demands of consumers, the record does not support the bleak short-term outlook for T-Mobile that AT&T has portrayed in its submissions."
T-Mobile has the cheapest and most flexible plans out of all the carriers. They have a solid phone lineup and interesting technology like WiFi calling that you can't really get anywhere else.
I hear so many people complain about their cell phone company but I have never had any issues with T-Mobile. I guess I will never understand why so many people stick with crappy service when there are so many better options.
