Call Forwarding on AT&T and T-Mobile: What We Could and Could Not Confirm
By Right On Call ·
AT&T and T-Mobile both support forwarding unanswered calls, but neither carrier publishes the whole picture, so most of what follows comes from third-party guides. We say so on each carrier. Treat the codes as a starting point and confirm them with a test call.
AT&T
Set it: Most guides give **61* then the number then # for no-answer forwarding. AT&T itself points wireless customers to the phone’s call-forwarding settings.
Cancel it: Most guides give ##61#.
We found no AT&T page that lists the no-answer code or a fee for it. Guides note that AT&T lines differ and that some need conditional forwarding switched on by AT&T first. If the code fails, call AT&T and ask for conditional call forwarding.

T-Mobile
Set it: Dial **61* then the number then #. Guides report you can set the ring delay before it forwards, from 5 to 30 seconds.
Cancel it: Dial ##61#. *#61# shows whether it is on.
The codes are consistent across guides, and guides say T-Mobile has you set them from the phone’s dialer, not the website or app. We found no T-Mobile page stating a fee. Metro by T-Mobile uses different steps.

What to know before you rely on texts
Texts to US phones need A2P 10DLC registration before carriers deliver them. We file it during setup; carriers approve it, usually in days but sometimes weeks, and we don’t control the timing. Until it is approved, no text reaches a US phone: not the caller’s confirmation, and not the summary to you. Calls are still answered, booked, and logged in your dashboard.
Test it
Call your own number from another phone and let it ring out. If the code fails, call the carrier and ask for conditional call forwarding.

Neither carrier gives us a price list for this, so ask what forwarded calls cost on your plan before you turn it on.
