T-Mobile
T-Mobile uses standard MMI star codes for call forwarding. Dial the sequence and tap Send.
Forward every call (immediate)
**21*{FORWARDING_NUMBER}#Forward when no answer
**61*{FORWARDING_NUMBER}#Cancel unconditional forwarding
##21#Notes
- On some T-Mobile prepaid plans, conditional forwarding (
**61*) needs to be enabled via the My T-Mobile app before star codes work.
