Carriers

The codes, by the phone in your hand.

Carriers did not agree on a single code. This is the cheat sheet we put in the app, written out so you can search it from the driveway.

Greasy hands dialing a star code on a phone inside a work van at twilight.

After you sign up we text you the codes with your forwarding number already in them. If you like doing it from a page, here is every recipe we ship.

AT&T, T-Mobile, most Android (GSM)

Missed-call — dial all three, wait for confirmation each time:

  • *61*1XXXXXXXXXX# — no answer
  • *67*1XXXXXXXXXX# — busy / decline
  • *62*1XXXXXXXXXX# — unreachable
  • *21*1XXXXXXXXXX# — always-answer (every call)
  • ##002# — turn the GSM forwards off

Verizon and many US cells

  • *71 + ten-digit number — no-answer and busy, phone still rings
  • *72 + ten-digit number — always-answer, phone does not ring
  • *73 — turn it off

iPhone

The Settings toggle is unconditional. It forwards every call. Use it only for always-answer. For missed-call, open the Phone app and dial the GSM or Verizon codes above like it was 1998. That is not a bug. Apple did not build conditional forwarding into Settings.

Questions shops actually ask

Why didn’t the code work?
Wrong family of codes for the carrier, or you used iPhone Settings in missed-call mode. GSM wants *61/*67/*62. Verizon often wants *71. Disable with *73 or ##002# and try the other set.
Do I include the 1?
GSM codes (*21, *61, *67, *62) want the full international-style number: *61*1XXXXXXXXXX#. Verizon *71 and *72 want the ten-digit US number with no extra 1.
