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.

Can you use Verizon sim card and put it in a t mobile phone and have the phone work for Verizon?
TMobile and Verizon are incompatible. As are every other two separate phone services. The only way to use a TMobile sim card in a Verizon phone, is to get the Verizon "unlocked". You can do this at most mobile phone shops, but not all of them and most likely not an official Verizon or TMobile shop. This will cost you.
Can a boost phone work with t mobile sim card?
I want to make sure I answer this question, after talking to tmobile, because there is sites that want to charge 40 bucks for unlocking your phone and I called T-Mobile asking if they would unlock the T-Mobile phone for use with boost Mobile and they said no problem. It takes about 24 hours and they email you the unlock code with instructions on how to do it. I guess it would be worth the money if you still had a contact or something but other then that... It's free!
