Hi guys so today I received my iphone 4s that I bought on amazon which is factory unlocked so i decided to try my tmobile sim which worked. I have a vietnamese sim card and when i put it in it doesnt search and the top left just says no sim. I put the vietnamese sim in my iphone 4 that is factory unlocked and it searched but says no service. Why doesn't it say that on my iphone 4s?
Got a tip for us?
