When using a SIM card with its SIM-pin security disabled, the system will work without
further configuration.
Setting a SIM pin helps reducing the risk of the SIM card being stolen and used. Use a mobile
phone to set the SIM pin, and there after configure it on the GX-device.
Settings → GSM modem → PIN code
Some mobile networks require manual configuration of an APN specially when roaming.
Contact your operator.
APN name can be configured in Settings → GSM Modem → APN.
