Motorola e5 play. Wifi calling disabled but still can’t send MMI.

Hi

My network is o2 and I am in touch with them also about this issue.
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# which I got from o2 forum but get the message “call forwarding connection problem or invalid MMI code”
Wifi is turned off and I have tried toggling airplane mode.
I can find no setting on the phone to disable Wifi calling

Called o2 cust service, they disabled Wifi calling in my account.
But still getting the same message.

What do I try now? I will go back to cust services 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

I didn't post in the dedicated E5 forum because it looks like there has only been one post there in the last 2 years.

I wanted this done, years ago, and the carrier needed to change my settings in their system. Good luck

Update, bought a new phone with Android 13 and I can send MMI on it.
