13.2 SIM card
The INSYS GPRS 5.0 serial requires a 3V/1.8V SIM card from a GSM provider for
operation. The SIM card is the identification for the network provider.
The SIM card must be placed into the carrier with the contacts downward to en-
sure that the contacts are on top of each other.
Change the SIM card only when the device is switched off.
