You can manage "Caller Identity Restriction" service using *311# USSD command.

After a successful request to connect the service, the phone number will be hidden by default. You will then be able to turn the service on and off at any time in the menu of your mobile phone. In this case, the subscription fee will be charged until a USSD request is made to deactivate the service.

If the “Caller Identity Restriction” service is activated on your phone and you want your number to be identified when calling another subscriber (for example, your friend), use the following method of calling:

*31#XXXXXXXXX or *31#+9989YXXXXXXX, where XXXXXXXXX – number of cell phone you are dialing.

If the “Caller Identity Restriction” service is activated, but it is disabled in the phone settings, use the following call method to hide your phone number:

#31#XXXXXXXXX or #31#+9989YXXXXXXX. Where XXXXXXXXX – called number.
