New Rule: Only YOU Should Have the Power to Change What You Pay –Introducing Un-contract for T-Mobile ONE
Today, T-Mobile introduced the Un-contract for T-Mobile ONE - and notched anotherindustry first with the first-ever price guarantee on an unlimited 4G LTE plan. Withthe Un-contract, T-Mobile signs, and customers hold all the power. Now, T-MobileONE customers keep their price until THEY decide to change it. T-Mobile will neverchange the price you pay for your T-Mobile ONE plan. When you sign up for T-Mobile ONE, only YOU have the power to change the price you pay.

They're trying to tell me it isn't clear (it is) and that their only obligation with "price lock" is to pay my final bill if i choose to leave because of a price increase. But, their price lock came later, and doesn't supercede their earlier promise not to increase the price to those who signed up for their "One" plan at the time.

This was the concern when they merged with Sprint, removing the 4th carrier from the board, that consumers would end up paying higher prices. I've spend several hours talking with T-Mobile customer care, but they do little more than read from "the script" despite my pointing out the uncarrier "un-contract" which is on their own web site, and they're choosing to ignore it. I've gone ahead and filed complaints with the FCC, the Anti-trust DIvision of the DOJ, my state's Attorney General, and my state's PUC. I imagine that a team of lawyers is chomping at the bit, readying a class action lawsuit, seeking injunctive relief, as well as some hefty damages for material breach of contract.
