Inserting your SIM card only takes a moment.
Different iPhones use different SIMs, so first make sure you know which type you need.
To use multiple networks, your iPhone must be unlocked - and all Raylo's iPhones already are.
Installing your nano SIM
Find the SIM tray on the right side of your iPhone
Insert a paper clip or SIM eject tool into the small hole on the SIM tray, then push in towards the iPhone to eject the tray.
Remove the tray from the iPhone.
Place the nano SIM in the tray. The angled corner shows you the right way.
Insert the tray back into the iPhone.
If you previously set up a PIN on the nano SIM, carefully enter the PIN when prompted. Never try to guess a SIM PIN. An incorrect guess can permanently lock your SIM and block phone calls or data usage until you get a new SIM.
