WIFI Calling Issue - The Number Entered Doesn't match or records.

There's no separate VoLTE add-on to add on your account, VoLTE is auto-provisioned in Koodo's carrier settings on newer plans.

Did you recently port or transfer this number to Koodo? On a freshly ported line that error usually means the transfer hasn't fully completed on Koodo's end rather than an actual Wi-Fi calling fault. As well, did you try enabling it while the phone had Koodo cellular signal? On Android you sometimes have to turn Wi-Fi calling back on after being out of network range, so I would try the activation upstairs rather than in the basement.

I would also reset the network settings on the S25 Ultra and try again. https://www.koodomobile.com/en/help/wifi-calling

Thank you ufor your replay.  

I did port my number from Rogers.  6 years ago.  I've only recently moved my office to the basement.  Yes I tried enabling while having coverage.  Same issue.  

 Network reset didn't work.  Same issue as before.  

Let me flag a rep to see if the VoWiFi is provisioned properly on your line.

I assume your S25 Ultra is a North American model? 

You will need to request a callback via koodo assist and a rep can investigate.

This has happened to me in the past and typically it fixes itself after a few weeks. But if you need wifi calling  now a rep will need to look into this.

Yes.  The s25 ultra was bought from Samsung in Canada brand new.   When it first launched 

That did the trick!   I am now able to make calls from my basement thank you so much.  

I’ve the same issue than AJRedman. Would it be possible to my number profile to my online account aka get the same fix?

Hello ​@JFB we’ve attached your number profile to your online account, please try to activate the Wi-Fi calling again. Let us know if it worked!

Thank you! The issue is fix, I was able to activate wi-fi calling.
