Hidden number
Some subscribers prefer to stay incognito, i.e. hide their phone number at an outgoing call. TezGSM allows that through a "Hidden Number" service. The service displays a message "Unknown number" instead of your phone number at the time of outgoing calls.
Service Activation
The "Hidden Number" service is activated at a written request from a personal account of a subscriber. The service is activated in a period of one day from the request moment. You will get a confirmation by mail when the service is active.
The service is free of charge.
