How to divert calls on Three.

This diverts only the calls you don't answer within 15 seconds — your phone still rings first. It works with Anseya or with any answering service.

Switch on

**61*01134960521*11*15#

Your Anseya number goes in the middle. Dial it once, from the phone whose calls you're diverting.

Switch off — just as fast

##61#

One dial and everything is back exactly as it was. Check the state any time with *#61#.

Step by step

Open the phone dialler — not a settings menu.
Dial the switch-on code and press call. Three replies with a confirmation.
Ring your number from another phone, let it ring out, and hear it answered.

If a code fails, nothing breaks — your calls simply behave as before. These are standard GSM codes rather than a Three feature. Where Three differs, the difference is printed here once we have seen it on a real Three SIM.

What it costs on Three: Three includes diverted minutes on most plans. Check your plan if you are on pay-as-you-go.
