SIM (Subscriber Identity Module) Card Information
To access a cellular network you must purchase a compatible SIM card. The GSM
modules have a SIM card slot located on the bottom of the PCB. The SIM card has to be
handled with care, avoiding any contact with the pins because electrostatic discharges
may damage the product itself. Please read the SIM manufactures instructions prior to
installing.
Do not insert or remove the SIM card when the product is in power saving mode.
The SIM interface complies with the GSM Phase 1 specification as well as GSM Phase
2+ specification for FAST 64 kbps SIM card. The module supports both 1.8Volt and 3
Volt SIM cards. The SIM card is enabled with the AT+CSDT command.
