Want to change carriers? T-Mobile is changing their tm fees and this will give you a way out without a ET fee.
From the Consumerist.
Want to get out of your T-mobile cellphone contract without paying a $200 early termination fee? Now you can. T-mobile is raising its text message rates August 29th to 20 cents per message. This counts as what is known as a "materially adverse change of contract." Under standard contract law, if one party changes the terms of the agreement in a way that financially harms the other party, then the contract is void. If the contract is void, so is any stipulation that you be charged a fee for breaking it (especially as technically they broke it first). You will have much better success arguing its a materially adverse change of contract if you are not currently in an unlimited text message plan. You don't have to wait until August to escape, members of the Slickdeals forums are already reporting success escaping without penalty. Stay tuned to The Consumerist for more information and tips on using this money-saving tactic.
