My device is a Motorola e5 “play”
I want to extend the ring time before divert to voicemail from the default 10s
I send the code **61*901*11*30# but get the message “call forwarding connection problem or invalid MM I code”
Wi-Fi is turned off and I have tried toggling air plane mode.
I can find no setting on the phone to disable Wi-Fi calling
Called 202, they disabled Wi-Fi calling in my account.
But still getting the same message.
What do I try now? I will go back to 202 on Monday during 9-5 and report an issue
Could it be my phone is not supported? I am a transferred Virgin customer but it wasn't a Virgin phone. Currently Android 8.1
Solved! Go to Solution.

Update, I bought a new phone with Android 13 and now I can send MMI code so I have messaged o2 support they can cancel this case, many thanks, I have no idea what could have caused the problem. Old phone? Android 8? About the pre requisite asking o2 network support to disable wifi calling, is that necessary for any phone ? I was wondering whether to ask support to re'enable it now ?

Try again after 24 hours when your account will have been updated.

Do any mmi codes work at all?
Try some listed in this guide Guide: All you need to know about O2 Voicemail 901

Unfortunately it appears you need to get back onto O2 @jiver2

It may very well be that your phone is just too old. You might want to consider upgrading.

Bambino, I am considering upgrading but that doesn't guarantee fixing the problem does it? I really need someone to tell me exactly why all these fixes suggested fail to work

I've never got these codes to work on my S20+ and S23+ so upgrading would be a gamble
