What to know about call divert on Onecom
Availability and charges
Onecom has not published a price for forwarding to another number in the linked guidance. Check availability, destination restrictions and charges with Onecom; sharing a network does not guarantee the same features or tariff.
Voicemail after cancellation
Vodafone's ##002# command cancels all active diverts. Ask Onecom how to restore its voicemail if you want missed calls to go there again.
One Net is a separate service
Onecom publishes separate portal instructions for One Net Business. If that is your service, use its One Net guidance rather than the mobile codes here.
Divert calls from your phone's settings
Your phone may also offer call forwarding in its settings, depending on your device and plan. The iPhone Call Forwarding switch sends every call on. Use a supported no-answer option if you want your phone to ring first.
iPhone
- Open Settings, then Apps, then Phone (on older iOS, Settings then Phone).
- Tap Call Forwarding and switch it on. If you use two SIMs, choose your business line first.
- Tap Forward To and enter the number calls should go to.
- Go back. A forwarding icon shows in the status bar while it is on.
Android
- Open the Phone app, tap the three-dot menu, then Settings.
- Tap Calls (or Supplementary services, depending on the phone), then Call forwarding.
- Choose When unanswered so your phone rings first and only missed calls move on.
- Enter the number, tap Turn on, and pick the right SIM if asked.
If the code doesn't work
"Connection problem or invalid MMI code"
The network did not accept the request. Check you have signal, turn off Wi-Fi calling and aeroplane mode, then dial the code again exactly as shown.
"Setting activation failed" or "unsuccessful"
The network refused the divert. Some plans block diverts to other numbers, and some networks want the number in international form. Check the notes on this page, or set it up in your phone settings instead.
Calls still go to voicemail
Voicemail is itself a divert, and only one can be active for each condition. Setting a new divert replaces the voicemail one. If calls still reach voicemail, cancel all diverts and set yours again.
Onecom call divert questions
How do I divert calls on Onecom?
The Vodafone code for all calls is **21* followed by the destination number and #. Use +44 in place of the leading 0. Confirm with Onecom that your plan accepts diverts to that number.
How do I turn off call divert on Onecom?
Vodafone publishes ##002# to cancel all diverts. These are host-network instructions; check with Onecom if the code fails.
Is call divert free on Onecom?
Check with Onecom. The linked guidance does not establish a rate for diverted calls on your plan.
Why might a Onecom divert code fail?
The codes describe Vodafone network commands. Your provider must also allow the feature and destination on your plan; contact Onecom if the network rejects the request.
