Quick answer
*67[number]: Place a single call as a withheld number. Dial *67 immediately followed by the number you want to reach, then press call. The person you are calling sees "No Caller ID", "Private" or "Blocked" instead of your number. The block applies to that one call only. Your next call is normal again.
