SIM Card

SIM stands for Subscriber Information Module. A SIM card stores the subscriber's personal information, GSM/GPRS radio
settings, security key, contacts, etc. SIM cards can be installed and removed from compatible mobile devices, enabling you to
switch devices without losing your personal information. SIM cards are obtained and activated by the network provider that
supports your GSM/GPRS network.
SIM Card Requirements
Before installing the SIM card:
• The SIM card must be activated by the service provider.
• The terminal must be powered down.
