I have a iphone plan with at&t in the us but im going back
for three months. Does anyone have any experience using a
singaporean SIM card in his/her iphone?
Could I simply take out my AT&T SIM card and put in a SIM
card from M1 (I have an M1 plan -- non pre-paid)? Would that work?
Or do I need to "jailbreak" it?
Thanks in advance!
