How to divert calls on BT Mobile
The short answer
On BT Mobile, dial **61*, then the number to divert to (with +44 in place of the first 0), then #, to divert calls not answered after 15 seconds. Use **67* when your phone is engaged, **62* when it's switched off, or **21* for every call. Dial ##002# to switch off all diverts.

Set it up for an AI receptionist
- Dial **61*[number]# and press call, so calls you don't answer within 15 seconds go to your receptionist.
- Dial **67*[number]# and **62*[number]# so busy and switched-off calls go there too.
- Ring your mobile from another phone and let it ring out to check it works.

Asked and answered.
Can I divert my BT Mobile number to an AI receptionist?+
Yes. Divert to the number we set up for your receptionist, ideally only when you don't answer, when you're busy and when your phone is off, so you still take the calls you can.
Does diverting calls cost anything on BT Mobile?+
BT doesn't list a separate charge for diverting. A diverted call to a UK number is a call from your plan. If you're outside your allowance, BT Mobile charges 54.37p a minute for calls to UK mobiles and 01, 02 and 03 numbers.
How do I check the divert is working?+
Ring your number from another phone and let it ring out. You should hear your AI receptionist answer, and get the email with the caller's details a moment after you hang up.
