Pro Tip
After dialing any code, wait for a confirmation tone before hanging up. This confirms the setting was applied successfully.
Forward All Calls (Immediate Forwarding)
Immediate call forwarding sends all incoming calls directly to another number without ringing your phone. Use this when you want every call forwarded.

- Open the Phone app on your AT&T phone
- Dial
*21*followed by the 10-digit forwarding number - Add
#at the end - Press Call
- Wait for the confirmation tone (usually 2-3 seconds)
- Hang up - forwarding is now active
Example: To forward to 555-123-4567, dial: *21*5551234567#
Method 2: Using *72 Code (Traditional)

Conditional Call Forwarding
Conditional forwarding only forwards calls when you can't answer - when you're busy, don't answer, or are unreachable. Your phone still rings first, giving you a chance to pick up.
Forward All Missed Calls (*004*)
This activates forwarding for all three conditions at once:
- Open the Phone app
- Dial
*004*[10-digit number]# - Press Call and wait for confirmation
Example: *004*5551234567#
Individual Conditional Forwarding Types

Forwards when you're on another call
*67*[number]#No Answer
Forwards after ~20 seconds of ringing
*61*[number]#When Unreachable
Forwards when phone is off or no signal
