Voicemail divert number

[Sha_rock]

What number do I enter to forward all calls straight to voicemail? Or is there a voicemail setting to do this?

The only number I can find searching help/forum is 901. I will try this but looking for confirmation / best solution.

I am pay monthly using a dual sim set up and want the work sim to divert whilst on leave but don’t want to switch it off altogether.

Many thanks.

I’ve seen this guide before so I suppose I want to do this part:

Divert all calls
To activate ** 21 * phone number # SEND

—If I put my own number will that go straight to voicemail? Or is there a number I should put there?

—I want to leave the SIM on but not accepting any calls whilst I’m on leave.

Thank you
