AT&T, T-Mobile, Mint, Metro & Google Fi
Mint Mobile and Metro by T-Mobile run on the T-Mobile network, and Google Fi runs over T-Mobile's network too, so all five carriers use the same GSM-style codes below.
Before you start: have your Kai number handy — it's in Dashboard > Phone System.
Turn Forwarding On
- From your business phone itself (not another line), open the Phone app keypad.
- Dial the code below for the mode you want, replacing the number with your actual Kai number (include the leading 1) and, if you want a different ring time, swapping 20 for 10, 15, 25, or 30.
- Tap Call, and wait for the confirmation tone or message.
- Kai will call your business line to confirm forwarding is working.
Only when you can't answer (recommended)
Covers busy, no answer, and unreachable in one code. Rings for 15 seconds before forwarding by default — long enough to grab it, short enough that Kai picks up before your carrier voicemail does.
**004*1[your Kai number]*11*15#
All calls
Every call on this line goes straight to Kai.
**21*1[your Kai number]#
Codes must be dialed exactly, including every * and #.
iPhone on T-Mobile or Mint Mobile: turn off Live Voicemail before you test — go to Settings > Phone > Live Voicemail and switch it off. Otherwise Live Voicemail answers first and the call never actually forwards to Kai.
Google Fi: Google officially recommends setting call forwarding in the Google Fi app rather than a dial code, but the GSM code above works over the T-Mobile network Fi uses. If it's rejected, use the Fi app instead.
Turn Forwarding Off
Dial the code that matches what you turned on:
Only when you can't answer
##004#
All calls
##21#
To check whether forwarding is currently on, dial *#61#.
