What to know about call divert on 1GLOBAL
Changing the divert number
1GLOBAL says you must cancel and deregister a divert before you point it at a new number. Dial the ## code first, for example ##21#, then set the divert again with the new number.
Pause and resume a divert
A single # cancels a divert but keeps the number for later, for example #61#. Dial *61# to switch the same divert back on without typing the number again.
Ring time and voicemail
1GLOBAL's voicemail page says you can set how long your phone rings before voicemail, from 5 to 30 seconds in steps of 5. UK voicemail is on 505.
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.
1GLOBAL call divert questions
How do I set up call forwarding on 1GLOBAL?
Dial *21* then the number in international form, such as +447700900123, then # to divert every call. For calls you do not answer, use *61* instead of *21*.
How do I turn off call forwarding on 1GLOBAL?
Dial ## then the divert code and #, for example ##21# for all calls or ##61# for unanswered calls. 1GLOBAL publishes a cancel code for each divert type.
Can I forward my 1GLOBAL UK number to a number abroad?
1GLOBAL says calls to a UK primary number can be diverted to another UK mobile or landline, and calls to a US number to another US number.
Why is my 1GLOBAL call forwarding not working?
Check the number is in international form, starting +44 for the UK, and that it is not a premium rate or emergency number. Forwarding is also not available if you have the 1GLOBAL Mobile Recording service.
