Angry T-Mobile customers have filed a class action lawsuit over the carrier's decision to raise prices on plans that were advertised as having a lifetime price guarantee.

"Based upon T-Mobile's representations that the rates offered with respect to certain plans were guaranteed to last for life or as long as the customer wanted to remain with that plan, each Plaintiff and the Class Members agreed to these plans for wireless cellphone service from T-Mobile," said the complaint filed in US District Court for the District of New Jersey. "However, in May 2024, T-Mobile unilaterally did away with these legacy phone plans and switched Plaintiffs and the Class to more expensive plans without their consent."

The complaint, filed on July 12, has four named plaintiffs who live in New Jersey, Georgia, Nevada, and Pennsylvania. They are seeking to represent a class of all US residents "who entered into a T-Mobile One Plan, Simple Choice plan, Magenta, Magenta Max, Magenta 55+, Magenta Amplified or Magenta Military Plan with T-Mobile which included a promised lifetime price guarantee but had their price increased without their consent and in violation of the promises made by T-Mobile and relied upon by Plaintiffs and the proposed class."
