It depends, if you're with a certain network (carrier)like [uk] orange, three, vodafone [us]at&t, sprint etc, then no... unless its unlocked, or if you get it from t-mobile, then yes, you will be able to use a t-mobile sim card.
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 :)
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
If you have used TMobile in the past, you can unlock your HTC Touch Pro2 by calling Tmobile. Alternatively, you can purchase unlocking software on websites such as eBay which will allow the unlocked phone to work with an AT&T sim card.
no you cant put tmobile sim card into a at&t phone- since it is a different company and provider the sims cards are toatlly different
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.
no it does not . it fits into a blackberry 8350I from nextel but it doesnt fit into any tmobile or att.
Only if the phone is not locked to t-mobile.
it should because all sim cards are the same (well within your compny like tmobile sprint and others).
You can put any SIM card in an unlocked cell phone.
You can - but - it will only work if the t-mobile phone has been unlocked !
