2 Pre-Installation
The CelluLine CGW-T unit contains a GSM engine. It therefore needs a SIM card from the
local GSM network provider. Its registration to the GSM operator is similar to the registration
of a mobile GSM phone.
The PIN & PUK code request must be disabled. Is this not the case, use any GSM mobile
phone to modify the SIM card or contact the local GSM Service Center.
Recommendation
We recommend disabling all call forwarding modes (in the events of busy, absence,
unavailability, etc.) and Call Waiting from the GSM operator, before installing the SIM card.
