What to know about call divert on JT
Writing the number on a JT mobile
JT writes the divert number in full international form. Its own example uses 0044 in place of the first 0, **67*00441481818818#, which diverts busy calls to Guernsey voicemail. The +44 form is the same number; if your phone will not accept it, type 0044 instead.
JT mobile voicemail
JT's Mobile Services team has to activate voicemail on your number before you can divert to it. Within the Channel Islands the voicemail number is 171. From elsewhere, Jersey customers dial +44 1534 555555 and Guernsey customers dial +44 1481 818818.
Busy and no reply in one code
JT home phones also have *66*, then the number and #, to divert calls both when you are busy and when nobody answers within 25 seconds. #66# cancels it. To change the number, set up the divert again with the new one; you do not need to cancel the old one first.
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.
