The business release path and phone number are read verbatim from T-Mobile’s business Port Out Protection page. Forwarding codes are inherited from the shared short codes page, which does not separate business lines. T-Mobile publishes no business-specific PIN expiry or completion timeline. Checked 2026-09-11.
Forward calls
1
Use the same short codes as consumer lines
T-Mobile publishes one set of call services short codes covering postpaid, business, and prepaid lines.
2
Turn on forwarding for every call
Dial **21*1 then the 10-digit number then #, and press call.
3
Add a conditional rule if you want a safety net
Use **611+number# for unanswered calls, **671+number# for busy, and **62*1+number# for when the phone is off or has no signal.
4
Turn it off
Dial ##21# to stop all-call forwarding, or ##004# to reset every forwarding rule to default.
5
Call your business number from another phone
Answering Agent listens for the call. When your agent picks up, the phone numbers step in your dashboard turns green.
Good to know
- T-Mobile does not publish a business-specific forwarding code set. The short codes page is shared.
- Short codes are mostly delivered to the primary SIM only and may not work on DIGITS lines, which matters for businesses using DIGITS for shared numbers.
Move your number
Start the move from Dashboard, then Phone numbers, then Add a number, and choose Move my number. Upload your latest bill and we read the details for you. Have these ready:Watch out for
- The business path is a phone call, not a self-service toggle. Budget for hold time rather than assuming you can do it in the portal at 6pm.
- Port Out Protection is per line, so a multi-line business has to release each line it wants to move.
- You still need the account number, the Temporary Port Out PIN, and the account PIN or passcode.
- Government accounts have to contact T-Mobile to start the process at all.
- T-Mobile publishes no business-specific port-out completion time.
