T-Mobile forwarding guide
T-Mobile publishes its codes on its self-service short codes page. Put a 1 before the 10-digit number.
| Action | Dial |
|---|---|
| Forward every call | **21*1[SRN]# |
| Forward when unanswered | **61*1[SRN]# |
| Forward when unreachable | **62*1[SRN]# |
| Forward when busy | **67*1[SRN]# |
| Turn off | ##21# / ##61# / ##62# / ##67# (matching rule) |
| Reset all forwarding to default | ##004# |
Framing note: all-call forwarding also routes the calls your shop would have answered itself. SavedRing is built for the calls your shop doesn't answer — busy, after-hours, overflow. If you forward every call, the "answer a second test call yourself" step in the test below does not apply — every call will reach SavedRing instead.
- Ring time before an unanswered call forwards is adjustable:
**61*1[SRN]**[seconds]#— 5 to 30 seconds. - For SavedRing, set 61 + 62 + 67 (the missed-call set) and leave 21 off.

The forwarding test call
Setup is not done when the code is dialed. From a different phone, call your business number and let it ring unanswered. SavedRing must answer in your shop's name, and a job card must land in your portal. Answer a second test call yourself, and confirm it stays with you. If any step fails, forwarding is not live — use the disable code above, and we fix it on a short call together.
