They say when the cell phone gods close a door, they open a window. Such is the case this morning for T-Mobile subscribers who aren’t enjoying their time with the carrier. As of today, T-Mobile is raising its overage rates to 45¢ per minute on individual plans under $59.99 and family plans under $89.99, and 40¢ per minute for plans above those price points. Since this rate increase is carrier-invoked and it constitutes a “materially adverse change of contract,” subscribers will be able to flee without the need to pay a hefty Early Termination Fee (ETF) — just as many did with Sprint earlier this year. What do you do if you want out of your contract? Get ready for battle, that’s what. As always with carriers, odds are good the some (or even most) customer service reps won’t even know about this option. When you call, be patient while the CS rep gathers info. Make sure that when you explain why you want to cancel your contract, you specifically cite these overage rate increases as your motive. If your rep starts giving you a hard time or doesn’t sound like he/she is going to put the pieces together, ask to speak to a manager or simply call back and start over with another rep. Oh, and hit the jump for a section of the T-Mobile contract that you may want to familiarize yourself with.
