Can you take your tmobile sim card and put it in a prepaid tmobile phone and it work on your plan?

Yes. if it is a tmobile sim card and a tmobile phone then this will definitely work. you will also be able to carry on with the same price plan and number you used before. If you currently have a Tmobile phone on a contract plan that is complete you can also just change your plan to a pre paid plan and keep on using the phone that you have. UPDATE: As of April 2012, TMobile prepaid phones may only connect to T Mobile towers, limiting your signal (since they also use ATT towers) and giving you varied signal strength depending on your location. So, it's best to unlock any prepaid phone. Ask T Mobile to send you the unlock code or pay someone to unlock your phone.

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.

When you put your sim card from your nextel sprint into an old tmobile phone it asks you for a subsidy Almost like a password. I do not know what a subsidy is.?

Actually it is a password that tmobile has to give you bcuz it is one of there phones just call tmobile and ask to talk to tech and explain that you got a tmobile phone and ur trying to make it a different company and you need the subsidy password and they are required to give it to you!! Not true, cell phone companys are not required to give it to you. Be careful, this will ruin the sim and you will lose all your contacts that are saved to it. Actually, cell phone companys do not have the subsidy lock, I work for one of them and we get this call all the time. The subsidy lock is from the manufactorer of the phone not the cell phone company.
