What to set
Let your team answer first.
Set all three conditional codes. Add a ring delay so you have time to answer: **61*1, the number, **20# gives you 20 seconds.
You get your Lippy number during setup. Forwarding doesn’t move or port your number, and you can turn it off at any time.
T-Mobile short codes
T-Mobile writes these with a 1 before the 10-digit number. Dial them from the T-Mobile phone.

- 1Open the Phone app on your T-Mobile phone.
- 2Dial **61*1, your 10-digit Lippy number, then **20# for a 20-second delay. Press call.
- 3Repeat with **67*1, the number, # and **62*1, the number, #.
- 4Call your number from another phone and let it ring to confirm Lippy answers.
Good to know
Before you switch it on.
- ##004# resets forwarding to T-Mobile's default, which sends missed calls back to voicemail. Use it to undo the setup, not to test it.
- Forward-all (**21*) overrides the other codes. Turn it off with ##21# if your phone has stopped ringing.
- T-Mobile forwards only to 10- or 11-digit U.S. numbers.
- Don't confuse *67 with **67*. *67 hides your caller ID on one outgoing call.

“I have been using Lippy AI for my notary business for about two months and I LOVE IT! The portal is amazing and the AI secretary says exactly what I thought her to say. I have had great feedback from clients and love knowing that I don't have to pick up every call. I also appreciate that they can filter spam calls.”
FAQ
T-Mobile forwarding questions.
How do I change how long my T-Mobile phone rings before forwarding?+
Add the seconds to the no-answer code: **61*1, the number, **, the seconds, #. T-Mobile allows 5, 10, 15, up to 30 seconds. For example **61*15551234567**20# waits 20 seconds.
What does ##004# do on T-Mobile?+
It resets call forwarding to T-Mobile's default, which usually sends unanswered calls to your voicemail. It undoes any forwarding to Lippy.
How do I check that T-Mobile forwarding works?+
Call your business number from a phone that is not on the account and let it ring. If you set forwarding for unanswered calls, Lippy should pick up after your phones ring. If you forwarded every call, Lippy should pick up right away. If the call still goes to your old voicemail, the forwarding did not save.
