FP5 Wi-fi calling not working

/e/OS Devices Fairphone

Dear community,

I have exyctly the same issue as described here: https://community.e.foundation/t/fp3-wifi-calling-no-longer-working

The only differences are the device (FP5) and OS version (3.0.4-t).

In a nutshell, wi-fi calling is not working but it has worked before. Living in a rural area with bad signal coverage this is a key feature for phone calls. Unfortunately I cannot tell exactly when / with what version it has stopped working.

Any pointers welcome. Thanks a lot.

the person in the linked FP3 thread really had necessary libraries missing and for other FP3 owners things worked. As in: your wifi call can be broken, but are you sure this is the same exact same case (“dlopen failed”) from looking at logcat errors?

There’s a gitlab wificall issue on a FP4 case, but if it’s not a general device issue, it’s very much scoped to device-carrier even. The issue gives general troubleshooting tips though.

Is it Congstar?

Indeed, that’s right. This issue concerns the Fairphone 4. However it does not appear to be related to a problem with the carrier. In fact, when the same SIM card is inserted into another device (an iPhone 8 in this case), WiFi calls work without any problems. Furthermore, other users have reported this problem with different operators.
It must be a problem related to version 3.XX specific to the Fairphone 4.

I don’t know if other devices are also affected.

Wow, that was a fast triple response, thank you all very much.

I haven’t checked logcat, I need to rephrase my statement, I guess. The symptoms are the same, I didn’t look so deep.

Thanks for the link. Could be related, the jump to /e/os 3 was also my first suspect but I cannot pinpoint to it.
I will try to put my SIM into my wife’s phone and tĂ©st it there.

I agree with that. My operator does not even seem to be contacted, the message just tells me to connect to a wireless network - but it is connected.

I don’t want to muddy this thread, it is on FP5 - but generally, if within the same device and version, other users can do successful wificalls, then it ceases to be a general device issue and gets to be more of a (carrier) config problem

I just did the test and swapped SIMS with my wife. With my SIM her phone uses wifi calling without any issue, that ultimately rules out the carrier.

A config issue - maybe. But since I don’t mess around in developer settings or anywhere else it was very likely not caused by myself.

Indeed, I had the same behavior with my FP4. Putting my SIM in my old I-Phone 8 and WiFi calling worked immediately.

So there’s a simple test to run to see if IMS VoWiFi service is well provisionned on your device:

Open the call dialler app, and dial *#*#4636#*#**

Then click on “phone information”. This will open a page about network configuration.
On the upper right three dots, click on ‘IMS state’.

Then check what’s the VoWiFi status. (in my case: VoWiFi: Unavailable)

Same here. What I am going to do with this information?

What device is it, FP4 or FP6?

You may publish this - and all related details - on the Gitlab issue: (see above)

It’s FP5.

I don’t have a gitlab account. Yet. On my way to create one.

Thanks again.

Just to be sure: Can you check your Wi-Fi calling settings? They are available in the public part of the phone settings, but quite hidden, and cannot be found with the search function of the settings.

Open Android settings > Select “Network and Internet” > Select “SIMs” > Your SIM card is listed (or several cards on multi-SIM phones). Tap on it. (This is IMHO not that intuitive because the toggle on the right suggests that you can just deactivate the SIM card with this entry.) > Scroll down to “Wi-Fi Calling” and tap on it > Configure as desired, i.e., activate “Use Wi-Fi calling”, set “Calling preference” to “Call over Wi-Fi”.

Is Wi-Fi calling available now if you check with *#*#4636*#*#?

I had to manually set my preference to Wi-Fi calling when I reinstalled my phone a couple of days ago.

EDIT: You can of course also use your favourite search engine for details :slight_smile:

Hi @Tentos,

also thank you for your contribution. But yes, of course those settings have always been like that.

It doesn’t accept my email (Tuta), so I won’t be able to post in gitlab. Maybe someone else wants to transfer the infos I have provided.

@Manoj Is the registration on GitLab still limited? Can you contact @Pampelmops so that they may open a bugticket there? (See also Create User in Gitlab)
