How to Turn Off O2 Voicemail and Check Call-Divert Settings
Disable O2 voicemail, verify call forwarding, re-enable voicemail, and troubleshoot conditional diverts without losing important calls.
Quick Answer
O2 voicemail is normally controlled through carrier service codes or account support. Codes and behavior can differ between O2 regions, pay-monthly plans, prepaid service, and business accounts, so confirm the instructions for your country.
- Check O2’s current official support page or app for the code used in your region.
- On O2 UK, 1760 has commonly been used to switch voicemail off and 1750 to switch it on, but verify before dialing.
- After changing the setting, call your number from another phone and let it ring.
- Check conditional call-divert status if calls still reach voicemail.
