How to put my sim card into my iphone 4s?
Look on the right side of your iPhone you will see a little whole use an hair pin or the pin that came with the phone and hold the pin straight a gently push and the tray should eject after that i suspect you have a micro sim card to insert into your device, just insert your sim and your done.
What the other guy said is correct. However, if it's a Sprint iPhone, it won't have a sim card slot.
