Insert a SIM card in your Nexus 4
Before you start using your phone, you may need to insert a micro SIM card. If no card is installed, the message “No SIM card” appears on the phone’s lock screen.
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 micro SIM card:
- Insert the SIM ejection tool that comes with the phone (or a thin pin) into the 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.
- Carefully reposition the tray in the slot and push it gently back into the phone.
Note that the phone may need to be restarted in order to acquire network signal correctly.
