Before beginning, please make sure that you are using the correct-sized SIM. For your convenience, within each Ultra SIM kit we include a 3-in-1 SIM (nano, micro, and standard size) and a SIM injector tool. Check your phone’s manual to ensure you are using the correct size SIM.
To Insert a SIM Card into an iPhone: Stick a pin into the slot on the side of your iPhone. This should cause the SIM card tray to pop out. Line up the SIM card by the notch to place it on the tray, and re-insert it back into the phone.
