GSP-1600 only; not GSP-1700. Historical cellular modes and dialing examples do not confirm current service.
How it connects
- GSP-1600 handset Check mode and signal
- Satellite antenna / sky view Confirm registration
- Registration / account service
Check satellite mode, signal strength and registration separately. A signal indicator alone does not prove the handset can make calls.
Lights and messages
- Check satellite mode, signal strength and registration separately. A signal indicator alone does not prove the handset can make calls.
A light is one clue, not a complete diagnosis. Match the indicator’s label and the on-screen message.
