Should Wi-Fi Calling remain on?

[Firegod]

Hey all

I'm struggling here with my Samsung A54 5G. I have a weak signal in the house and I have Wi-Fi calling enabled. The icon will sometimes appear in the status bar, and the dial icon will sometimes show the WiFi symbols on it too. However, it doesn't stay and often disappears. Is this normal? It seems to drop when the cellular signal improves but when I move back to somewhere with 1 bar, it doesn't return. I've tried resetting the network settings on the phone. I've checked various settings on the router just in case that people say can help (SIP ALG is disabled, Airtime Fairness is disabled, etc). It is annoying when on a call as I get a few seconds drop as it flicks around between deciding if it wants to be on Wi-Fi calling or not. I often lift the phone away and check to see if the icon has magically appeared or not. I thought it should remain on permenantly. Next step is to ask Three UK about it I guess.

Any ideas or tips about what I can check to troubleshoot further?

Thanks.

Yeah it does appear to be linked to signal quality. I've tested on the WiFi at work to rule out my home network and it behaves the same, more than 2 bars and it won't appear. I can force it by enabling aeroplane mode then turning on just the wifi. But that means you could miss out on text messages by being disconnected from the network.

I do use a vpn but I've tried with it connected and disconnected. I also have the dialer app split tunneled regardless. Not to say there could be some other system app that is linked that may need excluding that I'm unaware of. I might uninstall the vpn app completely and test.

I was under the impression all networks now support SMS over WiFi too? Although I guess you also need a compatible device.

I should do a test as if so, that would mean (at least at home) just keeping flight mode enabled all the time.

So I've been on to Three UK chat (I hate these chat windows but...) they said that it's nothing at their end and sounds like something to raise with Samsung. Now also interestingly, I was looking at one of the Three UK help articles for my model phone and I'm missing the VoLTE options that apparently should be there. So I've raised a ticket with Samsung through the Samsung Members app. If you Google "Samsung missing VoLTE" it brings back a lot of topics! However, during my fiddling this evening I thought I'd try the SIM in slot 2. Didn't help. Powered phone off and put it back into slot 1 (#OCD). Powered phone on... oh hello, I now have WiFi calling. And my signal is like 3 bars. Has it been fixed. No, short lived. The icon disappeared a few minutes later. I now have 1 bar signal and the WiFi calling hasn't returned lol.

I've therefore done an sms test with my bro and can thankfully confirm that it works when in aeroplane mode when using WiFi - excellent! And just tested a WiFi call with him and the signal was great and I could roam around the house between mesh nodes and the phone call remained solid. So that is my work around until I hear back from Samsung. In the house - use aeroplane mode.

Thanks.
