How to cancel Tmobile service?

I want to cancel it to switch to another company for the iPhone 5. Tmobile sucks. How do I cancel it, but I don't want to pay the $200 early termination fee. I already have bad credit, so this won't hurt. I'm am gonna put the $200 towards a security deposit for my new phone company.

I know their service sucks! I would just wait until my contract ends if I were you. But if you are rich, then go pay the cancellation fee. I'm a broke college student so I waited until my contract ended with tmobile to switch and get the iPhone 4s.

There are two ways that every phone company in America is required to have service with. You can either call T-Mobile with their service number and log into your account form their. Now, I have a Verizon Wirless account and they are high too, but maybe the websites are alike. Next go under "My account" (most likely will say My T-mobile), and go under "My Device". Here you can find all of the phones associated with your account and their associated numbers as well. Find the number/ phone that you would like to edit or remove plans for by finding the picture that should be of the type of phone you have. Next, click that or arround that should be a link titled (or a section called;) "Manage my device." Here you should be able to cancel a plan or the device currently assosiated with your account. I have never canceled a phone plan before, but I'm pretty sure there will be a "Cancelation fee" I do not know how much they will charge, but you should still review it in case. If the cancelation fee is just over rated then I would just wait until the plan for your phone expires.
