Can you put a t-mobile sim card in a AT&T phone?

I know you can, but is there any kind of unlocking you have to do? And will I lose any features? I want to do this with a pantech matrix

If you unlock it, I know a few low price websites that range from 2.99-15.99 and they work.


you also will need to add tmobile service network to use MMS and Internet

Email me and I can give you both.

you have to take it and have it unlocked it will work as normal
