How to Forward Your T-Mobile Number to Zinng
Use T-Mobile call forwarding to send your calls to your Zinng AI receptionist. Forward only the calls you miss, or send every call straight to Zinng. Setup takes about two minutes.
This is the number we set up for your agent (in your dashboard under AI Phone Agents → Agents). Type it once and every code below fills in automatically. Enter all 10 digits.
On a T-Mobile cell phone
Open your phone's dialer, type the code, and press Call and wait for the "Registration successful" confirmation.
Option 1: Forward only the calls you don't answer (recommended)
Your phone rings first. If you don't pick up, the call rolls over to Zinng so the caller still reaches your receptionist.
**61*[Zinng number]**20#
The 20 is how many seconds your phone rings before the call forwards. Use any multiple of 5 up to 30 (for example **61*[Zinng number]**10# for 10 seconds, or 30 for the longest).
To turn this off, dial ##61# and press call.
Option 2: Send every call straight to Zinng
Zinng answers all calls without ringing your phone at all.
**21*[Zinng number]#
To turn this off, dial ##21# and press call.
If a code doesn't go through, If a code does not go through, turn off Wi-Fi calling, make sure you have cellular signal, and try again. You should see a "Registration successful" message when it takes.
Metro by T-Mobile and Mint Mobile run on the T-Mobile network and use the same codes.
Confirm it works
From a different phone, call your T-Mobile number. If you forwarded only missed calls, let it ring through without answering; if you forwarded all calls, it goes straight through. Within a few rings, Zinng should pick up and greet the caller. If it does, you're all set.
Heads up: forwarded calls use minutes on your T-Mobile plan. Most plans include thousands of forwarding minutes to Canada and the US each month.
