IIIF150 Raptor VoWifi not working ('3' SIM works fine)

Have you ​@Knobbly, I never would’ve guessed

(future readers are gonna think I’ve lost the plot)

My house is in a radio dead spot - We don’t get a signal from any mobile provider. For this reason, we’ve previously used VoWifi when calling from home. This has worked perfectly for all of us using both Three and Lebara (Vodafone) SIMS.

Mine ain’t much better. I’m sitting on 1 bar (-122dBm 20asu) as I type. And it should work on iD too but I know why yours doesn’t. Read on

Bizarre thing is, that with iD Mobile,  my wife’s phone (Motorola G73) and son’s phone (Redmi Note 11) work fine with VoWifi, but mine doesn’t.

I could keep you waiting all night…. but I won’t. If you look at iD’s compatible phones list -

• What phones are compatible with the iD Mobile network? F.A.Q.

You see 2 of the 3 phones are on the list for both 4G(LTE) VoLTE and WiFi calling (aka VoWiFi):

But your mouthful of a phone -  IIIF150  Raptor - isn’t. So this might be the answer you didn’t want. But what I don’t get is that it worked on Three, so this is an iD created problem.

You’ve kinda proven it’s not the SIMs as any combo works in the other two phones.

Now that doesn’t mean it won’t work, it’s just not supported - but as yours doesn’t work I have no clue if iD would want to go down the route of adding it to their list. But it working on Three means iD must be doing something different
