Yes, You can put a T-Mobile in Simcard in any T-Mobile branded phone and it should work. The only problem I see that may occur is if the
Sim is to old, it may not work correctly, or give you a great signal, but I don't think that would be a problem. Grab a $20 phone from Walmart and throw it in and see what happens. If you get a
Sim card error, go to T-Mobile and have them swap the
Sim for a new one. You will be able to do anything else you can with a normal phone, accept MyFavs will have to be done on the computer, but you will still get MyFav charges for the numbers dialed if they are a MyFav!
