Wi-Fi Calling on Dropdown menu missing?

Did the most recent update for the phone and my dropdown menu no longer has the Wi-Fi calling button? Has it been moved elsewhere in the settings now (it’s not in Settings > Network and Internet either)?


Yes - the wifi calling quick setting has been removed as part of bringing in AT&T support. The feature itself is still there inside Settings > Network & Internet > Mobile network. However it seems its not working. So seems like a regression. Opened a Dev issue for this.

Interesting. I have also had the “Joyn” App suddenly appearing. I never installed it (and it never made itself known previously). It only shows up under the system apps list. It didn’t begin appearing until the most recent update and from what I can tell it may have something to do with those sorts of tasks.

Is this something that was packaged with whatever AT&T support you’re talking about?

Joyn app (RCS) was needed to comply with AT&T certification.

Ah - that’s kind of a shame that AT&T forces their bloatware onto the platform and it can’t be disabled, especially for those of us that don’t even use their service.

Is there something non-AT&T customers can do?

We are looking into some options for future SW releases.

ahoy all and first thanks to Teracube for moving toward a more sustainable phone, and one that is way more open!

i am seeing the same issue with the Wi-Fi callling not working here on Teracube_2e_16 but with a T-Mobile network:

  • when Airplane mode is activated Wi-Fi calling is disabled, even after re-activating Wi-Fi and Airplane mode
  • when Airplane mode is activated and then Wi-Fi (and then Wi-Fi calling again due to above issue) enabled, trying to make a call results in a “you must exit Airplane mode to make a call” message.

this is a pretty important feature for us so wondering if there has been any progress on a SW fix?

thanks again and take care!

Hi @waynedpj - welcome to Teracube forums. Yes - I tried this out as well on my T1 today and it works the same as you mentioned. Wifi calling is not working in airplane mode (with Wifi on).

I’ll check with the devs if there is something special in our code to block this. Do you happen to have any other Android 10+ phones that have this working?

ahoy @Sharad and thanks for the reply. unfortunately our previous phone was only supported until Android 5.x but it did have working Wi-Fi calling and txting. and while i will try to see if i can find an Android 10 to test, it is unlikely as most of our circles are caught in the Apple walled garden :slight_smile:

thanks again, w

My wife’s Pixel 4a with Android 11 works properly (Airplane mode ON, wifi ON, and it dials out). It does look like Android moved the wifi calling selection into settings for 10 and up, but it should be on by default.

I think this might be another side-effect of the Joyn ap, as wifi calling worked prior to the firmware update when the Joyn ap got forced on us. Some Google searching says wifi calling is both hardware and provider dependent, and so I wonder if AT&T gimped the feature if you refuse to use Joyn.

The Joyn app has nothing to do with Wifi calling. As I mentioned earlier, AT&T enforces no wifi calling policy on all BYOD phones. Hence we had to specifically configure it such that it is not shown for AT&T (it’ll not work even if its there).

Any update, eta for a fix, anything on this issue?

I am relying on WiFi Calling to be reachable on a German number (O2 SIM that worked until I installed the 2e_16 upgrade. Now I am dead in the water. This is a dealbreaker for me using Teracube phones. Please fix this

I use AT&T on a Samsung S8 running Android Pie, and WiFi calling works fine.

What? A fundamental component of any modern phone has been borked to cater to just one carrier in the world? Not to make too fine of a point, but screw AT&T. If I wanted to be locked into their terrible service, I would’ve signed up for them a long time ago. This literally costs me money. Now when I’m out of the country on business, instead of being able to connect to WiFi and make standard calls I have to pay to roam.

The camera issues are a nuisance; this is a basic operational failure. Completely unacceptable.

while i understand that there will be growing pains with a new company and products, we just invested in 2x 2e phones to support the mission, success, etc. of Teracube. and like others the use of Wi-Fi calling/txting is essential. what’s more is that it was working recently before the latest update. @Sharad if there is not a quick fix/update pending, can we at least go back to a previous version of the system software where Wi-Fi calling works, and if so how?

The behavior seems NOT unique to Terracube: On a Ulefone Armor X8 with Android 10, over Ting/T-Mobile, wifi calling does NOT work if in airplane mode, and wifi on. As with @waynedpj , I get the message: “you must exit Airplane mode to make a call”
