What if your daughter lost her tmobile phone Can you buy a new sim card and put it in an old tmobile phone but still keep her number for the lost phone?
You can do this as long as the old phone works with the tMobile network (or is unlocked to work on both AT&T and tMobile). But you need to call tMobile to have them active the new SIM chip. Basically, they need to connect your daughter as a customer to the new SIM. You should be able to take your old phone into any tMobile store and they should do this for you. Cannot say if they will charge you a small activation fee but it should not require another 2 year contract. They may try to push a new phone on you for free or small price so they can lock you into a new 2 year plan.
