A SIM (Subscriber Identity Module) Card contains all of the information associated with your iPhone. If you would like to change mobile devices, but you want to keep your existing information, you can remove the SIM card from your iPhone and insert it into another phone. You will need a SIM removal tool or a simple paperclip to remove the SIM card.
Obtain the correct SIM card. The iPhone 6 models use a Nano SIM.
Locate the SIM port. The SIM port is located on the right side of the phone, about halfway down the edge.
Insert a straightened paperclip or SIM eject tool. Insert the straight end into the hole next to the SIM port. Push gently to eject the tray. Remove your SIM card from the tray. Be sure to reinsert the tray if you are sending your phone in for warranty service.
