Can a t-mobile SIM card be used in other cell phones from different carriers? like the LG chocolate?
I have a t-mobile plan that also came with a SIM card from that network. I have no clue, but is it possible to use phones from other carriers with my SIM card?

if the phone is unlocked it wont be a prolblem
Any cell phone that is not “locked in” with any specific provider or SIM card. As long as the frequencies are compatible, you can use any SIM card with your phone. If you have purchased or rented your handset through another source, particularly one of the major carriers, you will most likely not be able to use a different SIM card in your phone.
Yeah, as long as it is unlocked, but since the Chocolate is Verizon-Exclusive, it doesn’t use SIM cards. Hope this helps.
