I had a Samsung Galaxy 5 on EE but bought from the defunct Phones4U which, not having EE firmware, did not work with wifi calling.
Last week I replaced the phone with a OnePlus 6 which is also not on EE firmware but on setting it up I got a message that wifi calling was " now set up on your phone" and ready to be used.
OnePlus 8.1 android is virtually vanilla should that make any difference
Just wondered if requirements had changed or whether the experts here might have an explanation or it was just a standard text that didn't actually check whether or not the phone complied.
I cannot easily say whether it works or not as I get a good signal here and would normally be on standard 4G (and not living in London don't use the underground)

It's handset specific.
Some handsets you have to buy direct others it doesn't matter.
One plus 6 is a handset EE can't alter the firmware on as it is stock android. So this wouldn't be something EE would block from.using the service.
The S5 on other hands is one that you have to buy direct.
S8 you don't any more but at the moment the S9 you do.

Yes, understand that it "shouldn't" take wifi calling so that was why I wondered why I got the text (from EE) saying it was "now set up on your phone. You can now use it to make calls" etc.
Just an auto text message maybe?

It's probably cuz the OnePlus 6 has Oreo 8 firmware but the S5 had something earlier.

It has nothing to do with the firmware.
The S9 came with Oreo.

@BrendonH: I not saying all phones with Oreo have it, but just some & perhaps this 1.

Thanks, @chistery, that's useful to know. Are you sure it is both VoLTE and VoWiFi that don't work outside EE?
I have an unbranded S8 running on O2 that has VoLTE but not VoWiFi.
@Northerner has an unbranded S8+ running on EE that has both VoLTE and VoWiFi.

@XRaySpeX I don't think I recall anyone else saying they've had either working on other networks, just EE and BTMobile. I know Vodafone is a no. It may be possible by rooting and tweaking the build.prop files, but not out of the box.
