Do you need to unlock your mobile phone before you can buy a prepaid card in thailand?
I am
a t-mobile phone user and will be going to thailand for a few months. when i am
in bangkok, i
want to
buy a prepaid phone card.
does anyone know if you you need to unlock your mobile phone before you can buy a prepaid card in thailand? if your phone is unlocked, then, when you are back in the uk, is there any problem with your current network?
