At A Glance

This Alert Affects:
T-Mobile customers whose wireless plan rates increased despite being advertised as having a price lock or “un-contract” guarantee.
What’s Going On?
Attorneys working with ClassAction.org believe T-Mobile may have violated consumer protection laws by breaking its promise not to raise rates for certain wireless plans. They’re now gathering affected customers to sign up for legal action.
Which Plans Are Included?
The T-Mobile ONE, Simple-Choice, Magenta, Magenta Max, Magenta 55+, Magenta Amplified, Magenta Military and any other T-Mobile plan advertised as having a price lock or un-contract promise.
What Am I Signing Up For, Exactly?
You’re signing up for what’s known as “mass arbitration,” which involves hundreds or thousands of consumers bringing individual arbitration claims against the same company at the same time and over the same issue. This is different from class action litigation and takes place outside of court.
Does This Cost Anything?
It costs nothing to sign up, and the attorneys will only get paid if they win your claim.
How Much Could I Get?
While there are no guarantees, certain states’ consumer protection laws provide that people whose rights are violated could be owed $100s.
