WiFi calling not working

[Musgrave]

I've an iPhone 16 Pro running iOS 18.6.2 with Three 64.2 and WiFi calling doesn't work on my Community Fibre internet. I cannot make or receive calls. As soon as I disconnect WiFi it works. 
Anyone else? Is this a Three issue or a Community Fibre issue?

I’m having the same issues with Three and Community Fibre, my iPhone displays WiFi calls, but all calls into and out of don’t connect. If I disable WiFi the calls connect and I can receive them. I’ve updated the OS to 18.7, three network settings show 64.2 and I’ve erased network settings but still get the same problems.

I’ve a o2 eSIM on the same phone, when enabling WiFi calling on this network, I have no issues.

Hi @Musgrave,

Is this issue still persisting for you? Have you been able to test your connection with any other Wi-Fi to help determine if it's specifically an issue with the CF connection, or a general issue with connecting Wi-Fi calls?

Thanks,
Jonathan

It's been the same for my wife and me for the past two or three months, both using iPhone 16s, with Network Provider shown as Three 64.2, trying to use WiFi calling on Community Fibre. We can't make or receive calls when WiFi is enabled on the phones.

I keep saying that this is down to Community Fibre setup... my wifi calling (over BT) still working flawlessly since whenever was the last Three outage...

This has been going on for more than two months now (see my other threads) for dozens of Three customers on Community Fiber. You can try all of the temporary fixes that people describe here, but it will not give you a permanent solution. A Three engineer told me to give up on those temp fixes Three Mobile have told me on the phone multiple times that it is a known issue that they are trying to resolve. It have no timeline for when it might be resolved. Haven’t gone two months not being able to make a phone call from my house. I am now leaving the service.

I agree, no other network provider has this problem, just Three, I can't understand how Three can't get to the bottom of it.

Yes, I went to a Three shop because I couldn't get anywhere on the phone to Three. The person helping me at the store connected my phone to the 2 broadband providers they had and it worked, I've been trying for weeks with  no joy and just a few minutes ago I missed a call from your complaints dept because I have no signal here hence the need to get this fixed asap

sorry just to understand a bit better. Do you get the "3 wifi calling" indication on the top of your screen?

[Paolo_B]

Yes I do, its definitely on

@Paolo_B as you are posting under this topic I assume you are on CF(Community Fiber)? And with an iphone?
