Before you start using your phone, you may need to insert your Micro SIM card. If no card is installed, the message "NO SIM CARD - EMERGENCY CALLS ONLY" appears on the phone's lock screen.
Insert a SIM card
The SIM card tray is located on the left side of the phone below the volume button. The eject button is a small hole just above the tray door.
To install a new Micro SIM card:
Insert the SIM ejection tool that comes with the phone (or a thin pin) into the eject button hole, and push firmly but gently until the tray pops out.
Remove the tray and place the Micro SIM card inside it, with the contacts out and the angled corner to the right. There is only one possible way to fit the card snugly into the tray.
Carefully reposition the tray in the slot and push it gently back into the phone.
Note: Your phone's IMEI identification number is on the SIM card tray. You may need this number later to identify your phone for service purposes. Write down the IMEI number or take a photo of the label on the product box.
