Yes you can. You can put any tmobile sim card into any tmobile or unlocked phone and it will work perfectly. Although you may need to add some features to your plan :)
You can put any SIM card in an unlocked cell phone.
it should because all sim cards are the same (well within your compny like tmobile sprint and others).
i dont
When you buy a tmobile phone it camoes with a sim card. If you already have a tmobile phone and break it you can buy a pre-paid phone and put your old sim card in it
is needed
No you can't. they use different types of technologies CDMA (VERIZON, SPRINT, CRICKET) and sim cards use GSM (TMOBILE, AT&T etc..) they are simply not compatible technologies.. sorry!
phones from at&t or tmobile can be used with a Simple Mobile sim card.
no, you dont. you can jailbreak your iphone and run it on tmobile's network, if you have a tmobile sim card. but on tmobile, you cant have 3g speeds, only 2g.
Yes, your phone number will still be the same, if you pay for text or internet, it should work also, if its doesn't you can try a hard reset i have a sidekick lx and going to a sidekick 2008.
