iPhone and Android users you can now block your number when calling someone.
Dial *67 before the number you are going to dial.
It will appear as no caller ID, blocked or private on the other persons end.
You can also go in settings to block your number for every call you make.
If you do that but need to temporarily unblock yourself dial *82 then the number.
Have you ever blocked your number to ‘catch someone’ in a lie or something?
