Call diverts on O2
On O2 the standard divert codes are the usual way, and you dial them from your phone's keypad like any other number. O2's own help does not print the codes, so they come from O2 customers and guides that use them.

How to divert calls on O2
- Open the Phone app and switch to the keypad you use to dial ordinary numbers.
- Dial each code from the table below, one at a time, with the number your calls should go to in place of NUMBER (a 0 and ten digits), and press call.
- Test it: ask someone to call you from another phone and do not answer. The call should end up where you diverted it.
Call divert codes
When you don't answer within 5 seconds
**61*NUMBER**5#
You can set the ring time anywhere from 5 to 30 seconds (in steps of five).
When your phone is off or has no signal
**62*NUMBER#
When you're already on a call
**67*NUMBER#
Turn off all forwarding
##002#
Where it says NUMBER, enter the number your calls should go to in its national form: a 0 and ten digits, with no spaces and no +44 (a plus sign can get lost when you dial). You dial the code from your phone's keypad like any other number.
Already use Lorela? You will find your ready-made code, with your Lorela number in it, after you log in: in Settings under Number and forwarding (on the web and in the Lorela app), or in the forwarding guide.
What to know about O2
A moderator of the O2 community and a university IT guide both give ##002# to cancel every divert, and the guide prints the code for unanswered calls with a ring time in steps of five seconds. O2's own page on cancelling all diverts describes the setting but prints no codes.
We have not found how O2 charges a diverted call or whether pay as you go can divert to another number, so check your plan. giffgaff, Tesco Mobile and Sky Mobile usually run on the O2 network, but check with your provider that its codes match.
Common questions
Does O2 publish these codes?
Not on its own help pages. The codes are the standard ones, confirmed by O2 customers and a university guide. Test one before relying on it.
How do I turn diverts off on O2?
Dial ##002#, which clears every divert, including the one to voicemail. To turn off one situation, use ##61# for unanswered calls.
Will I lose my voicemail?
Only for the calls you divert. A divert for unanswered calls replaces voicemail for those calls, and ##002# brings it back.
Does this work on pay as you go?
We have not been able to confirm it for O2. Dial the code and test it. If your calls are not diverted, a pay monthly plan is the safe route.
