SIM Card Installation
Short for Subscriber Information Module, a SIM card stores the subscriber's personal information,
GSM/GPRS radio settings, security keys, contacts, etc. SIM cards can be installed in compatible mobile
devices, enabling you to switch devices without losing personal and setup information.
SIM Card Requirements
Before installing the SIM card:
• The service provider must activate the SIM card.
• The terminal must be powered down.
Note: If no SIM card is installed, you can still make emergency phone calls (e.g., 9-1-1).
