1.2 SIM Card
The SIM (Subscriber Identity Module) card identifies your device to
the wireless network. You can't make or receive phone calls without a
properly installed SIM card unless it's an emergency call (911).
You don't need to power off your device before inserting or removing
the SIM card.
Note: Your phone only supports NANO SIM cards. Do not attempt
to insert other SIM types like mini and micro cards to avoid damage
to your device.
