I switched from AT&T to T-Mobile when I got my OnePlus, so I can't say for sure, but I believe AT&T limits WiFi-Calling to certain devices, and even then, only the AT&T variants of those. (Mostly newer and from big name brands e.g. Apple, Samsung, HTC, LG). Since to my knowledge even an unlocked Galaxy s8 won't have WiFi calling on AT&T, it is unlikely that any OnePlus device will ever have that ability.

Yes, I remember reading you can NOT do Wi-Fi calling on att with bring your own device.

Just another reason TMobile is the real deal
Yeah, or any of their mvno's!

I was with family today in Anaheim, a highly populated, very modern city I mean Disneyland is there.

My dad has AT&T, I have mint sim (a t mobile mvno) I had near 70-80db signal, he was bouncing between 120 and up.. Had no signal whatsoever for extended periods of time. And with their low band frequency purchase, it's only getting better. It's anecdotal evidence, but still..

While I don't think t mobile offers the best network, I strongly feel they are going to get there in a couple years should they keep this up..

Att does not allow the 1+5, albeight the technology is there, to do VoWifi or VoLte. They reserve those features for devices solely purchased from Att, ie Only branded devices. If the Le eco does work it out of the box, that's awesome. Don't tell Att that, lol. I got into a huge argument with Att NatCs and filed troubleshooting tickets only to be told, sorry, since it wasn't purchased directly, no work. I have since made the move to TMobile. Im in NJ as a reference. And to be honest, I find the voice quality vastly better to what I had with Att, with hd voice too. I've hit some spots with little to no coverage, usually at a friend's house but my VoWifi kicks in and I have service once again with no issues.

Many retail/unlock mobiles have "Wifi Calling" function but not any menu entry to enable , The APP can check the hidden function and enable it if can use.

Interesting app. But I'm not sure it works.

I install it, on my un-rooted OnePlus 5, then run it - hey! there's a convincing looking setting, for wifi - and so I activate it. But everytime I return to the app, the setting is 'off' again. Does that mean the setting doesn't 'stick' and my phone (running on AT&T) cannot actually use wifi?

Plus, it looks to me as though the app has to remain running (although there's a setting to not display the notification icon, it doesn't seem to 'stick' either).

Ultimately, I cannot seem to get my phone to actually make a wifi call. For this reason, I'm skeptical this app is able to enable wifi calling, on the AT&T network.

I just called ATT.
I want to upgrade to the 5 and i need it to call over wifi as most of the time i'm in a rural situation with no coverage.
The ATT tech support said there would be no problem.

I hate to say it, but they lied (unless there's been a drastic change as-of-late).
Even if you can get them to provision your 5T, it'll only "stick" for a minute or so, and then revert.

AT&T is somewhat "famous" for their lack of BYOD (non-branded) WiFi call/text support. The exception is iOS devices, and a couple of "certified" Android phones; I think the HTC 10 (or maybe it was the 9) was an example, you can probably count these on one hand.

AT&T has an issue like this forever, as they do not wish to give that option to all. That is like a drop in profits, and drop in latency and lags. Anyways, too long to explain, but the gist is, they will have loss if they allow full coverage (at least loss on journal entries)..
