Since T Mobile and ATT are both GSM based isn't it
possible to use phones and SIM cards between BOTH
systems?

Neither T-Mobile nor ATT currently sell unlocked phones, but will
unlock phones at the end of a contract.

Any way to unlock them yourself?

They'll both actually do it 90 days, as long as you're a customer in good
standing.

Unless it's an iPhone, then AT&T's answer is simply"no."

Yes, OR, buy an unlocked phone and use the service you choose.


OK but appears that ATT wont let me have a monthly pay
plan even if I provide my own phone, correct?
