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 understand, and I know how annoying this situation can be—you’re stuck between two providers pointing fingers at each other. Recently, I’ve seen a few posts from users with CF, so maybe CF changed something, and for some reason, Three’s Wi-Fi Calling doesn’t like it.
From what I’ve read online, it could be related to CNAT and fragmentation. But based on your replies, you’ve confirmed that your phone worked with Three Wi-Fi Calling when you visited a Three shop. The assistants connected your phone’s Wi-Fi to two other broadband networks, and there were no issues between Three and those providers.
I rely on Wi-Fi Calling at home too, and so far, I have no complaints (I’m with BT). There are also other users here who rely on Wi-Fi Calling, and I’m sure they would be raising alarms if it wasn’t working for them and Three had messed something up.
In my opinion, it seems like something went wrong on CF’s end.

Two top-level engineers at Three have confirmed to me the issue is on Three’s side - not Community Fiber’s side. This is part of the reason I’m leaving Three… mainly because they have confirmed me that there is no timeline or even a target to fix the issue, but also because they can’t even communicate to customers broadly that the issue is on their side. And they leave us on this forum, trying to guess what to do or who is at fault, even though they have confirmed it’s on their side.

I've just discovered this entire set of threads - I'm having big problems too but I'm not on CF I'm on Hyperoptic so this must be a Three problem. I have just moved into a basement flat and the phone signal is poor, I cannot currently receive or make calls at all - my wifi calling is enabled, showing in the corner but not working either. I really don't want to change carriers but I can't stay with three if I'm not able to make or receive calls in my own flat. Can anyone help?

I'm on Plusnet FTC with the same iphone 6s for years.
WiFi calling stopped working last week and Three seem to have no idea why.
Wifi calling works with the same phone and WiFi connection when using Labara.
I'm getting more than a little irritated by this.
