i use a motorola prepaid cell phone here in the US. the phone comes with a removable sim card in the back.

i might be travelling to Thailand this summer and was wondering if the phone will work over there.

could i just buy a sim card there, put it in, charge it up. will the phone work?

i don't know how sim cards work.

also, what is 'unlocking' a phone mean?
