How to forward calls
- Enter the number you want calls forwarded to.
- Choose when to forward: all calls, no answer, busy or unreachable.
- Dial the code on your mobile and press call. You'll see a confirmation.
- To stop, dial the matching 'turn off' code.
On an iPhone
Settings → Phone → Call Forwarding → turn it on → enter the number. This forwards every call. For missed or busy calls only, dial the codes above from the Phone app.
On Android (Samsung, Pixel and others)
Open the Phone app → ⋮ menu → Settings → Calls or Supplementary services → Call forwarding. Choose always, when busy, when unanswered or when unreachable, and enter the number. The exact menu names vary by phone; the codes above work on all of them.
BT and other landlines
On most BT lines, dial *21* then the number and # to divert all calls, and #21# to cancel. For busy use *67*, for no reply *61*. Call Diversion may need switching on, and diverted calls are charged, so check with your provider. Other landline providers often use the same codes.
Never miss a forwarded call
Forwarding only moves the problem if nobody answers the other phone. With Pathir, you forward to your Pathir number and every call is answered 24/7: questions answered, appointments booked, and urgent calls put through to you. See what missed calls cost with the missed call calculator.
