I’ve looked by all the posts about this subject though haven’t found what I’m seeking for.
Can any one discuss it me if I can operate my prepaid Sim label in the Iphone 3GS, afterwards turn on and pointer and 2 yr stipulate as normal?
I have the possibility to buy a used 3GS though need a Sim label for it. I DO devise to turn on the phone as normal and pointer the 2 year contract. Then operate the phone as the manufacturer intended.
