Xperia VIII can't make mobile calls

[MrTek]

I moved to Rogers from another provider for better coverage in my area.  I have an Xperia V iii which worked on Telus towers.  Moving to Rogers, I have no problem with LTE/4G/5G data but cannot make mobile calls.  Soon as I try to make a call I just get dead air for about 30 seconds, then the signal drops (! sign).  Soon as I hang up the phone I get signal back again for LTE data.  I've done the phone settings using the *#*# menu and have tried manually selecting every band and the only change I have seen is the phone immediately hangs up when trying to make a call, others just do nothing.

tldr; data works but mobile calls don't.

It sounds like your device is not compatible with Rogers implementation of VoLTE. If you turn off VoLTE, it should drop to 3G for incoming and outgoing calls. This is only a temporary solution until the 3G shutdown starts to make its way to Canadian carriers. If you believe your device is compatible with the Rogers implementation of VoLTE. Give support a call and have them check to make sure your device is properly provisioned for VoLTE.

Thank you for the input, I will check that out.

Follow up, by going into the phone's *#*# advanced functions, there is a slider for VoLTE provisioning which is turned off, and also greyed out so it cannot be turned on.  However in the details section of the phone's network connection, it shows "VoLTE: LTE" so I'm not sure what that means.

Makes me wonder if the old provisioning from Telus is stuck in some way. Have you tried a Network Reset on the device?

[MrTek]

I believe I did at first but will try it again.  Thanks for the ideas.  I really hate having to go back to my old old phone which is 2 OS versions behind and doesn't get updates anymore, but it works.

I decided to do a full factory reset on the phone, and it did not make any difference in the settings - still no VoLTE available. I think the only remaining solution is to call Roger's tech and see if they can add VoLTE provisioning based on the SIM and IMEI.
