How easy is it to transfer t-mobile account?

I had amazing Credit score and i basically messed it up the past year, as a result i know i will not pass the T-mobile credit score to get the iPhone 5s (Worth about £700).

So i'm convincing my mother to get it for me but i want to have total control of the account, i heard they allow Account transfers, do they allow it?

Try Consumerscellular.com no contract is required and you can cancel at any time. Its cheaper then any I've seen and have had no failed calls. You can buy Smart Phones from them too at cheaper prices. An Android you can change batteries in such as the Sam Sung Galaxy but you can't do that to an Iphone Its nice having a spare battery all the time when I don't have time to be charging.
