When you’re getting ready to make a call and you want to turn off caller ID, you can just slightly alter the number you’re calling.
Dial #31# before the number you want to call, and then dial the rest of the number like normal.
For example, if you’re calling the number 0123 456 789 from your mobile phone, you can call them without showing your caller ID by dialling #31#0123 456 789.
Blocking your caller ID is super simple this way, but you do need to know the number you want to dial so that you can type it into the phone. You might want to hide your caller ID completely or automatically block your caller ID so that you can dial any number without having to put in those extra digits.
If you want to turn off your caller ID or if you’re wondering how to turn on no caller ID on your phone, you have to make changes to the phone’s settings.
