Wifi Calling not working on on of two phones on contract

Aircub128 — Sat, 07 Jun 2025 22:08:36 GMT

I have two Phone a Iphone 16 and Iphone 15 both running IOS 18.5. The Iphone 16 has stopped wifi calling. I have done all the normal resets, reboots, and even reloaded a new esim into the phone, but still no Wifi Calling. If I put them both into airplane mode the 15 has wifi calling the 16 does not. both have wifi calling turned on in the esim settings.

I have contacted support and they say it must be the phone, contacted Apple and they say its Three

I need Wifi calling as the phone signal is 1 bar or nothing most of the time.

Any ideas would be appreciated

Typical support agents pointing fingers at eachother...

WiFi calling is controlled by the phone, so you can only force them by enabling airplane mode and then switch on WiFi only, or disabling cellular coverage and leaving WiFi on ( not sure if iPhone has this last option)

Have you tried to toggle the WiFi button a few times? And forget the WiFi network and join again? By any chance do you have sky broadband?

Sorry I missed something on my suggestion, I meant have you tried toggle the WiFi calling button a few times...

There is/was something wrong with sky broadband...

Checked my second phone this morning and it had a banner, "Carrier Update", so I did the update and bingo I have no Wifi calling on that phone now as well.

So it looks like the most recent Carrier Update has killed my Wifi Calling, now on both phones. Is there anything that can be done to go back to a previous version?

I can confirm that since the recent carrier update WiFi calling has stopped working on my iPhone. I’ve tried all the usual remedies and am in the same location (home) as per usual. If you look at the carrier update it facilitates voice/sms and rcs (messages). No mention of the ip carrier needed for WiFi calling.

hmm that is strange... Yesterday morning I noticed that my android phone was not on wifi calling (and usually it is), but then in the afternoon/evening was back on it.

Have you powered it off for little while and then on again and see if picks up the wifi calling or even force it(by using the airplane mode on and then wifi on)?

Yes done all of that including resetting network settings. I’m not too bothered but other people may be.

I have the exact same issue after the carrier update Wifi calling stopped working instantly on two phones. I did call Three Not even able to gain agreement of the issue, even explaining it very slowly. This is definitely not a phone issue is definitely the network. I have several phone lines on my device and Wi-Fi calling works fine when I enable those networks. Where I live, I get one bar signal or no signal inside the house so Wifi calling is really useful. I do not see anything that we can do as customers until they push another update. The Three customer support were like no we don’t send carrier settings. Update…

One thing I will say you can try it just going into settings general about When you do that, the phone does actually look for new carrier settings. That way you won’t have to wait until they push it.

If anyone can, please post if you can hear any news about resolution for this from Three, that would be fantastic and have a great day.

Spent most of yesterday afternoon on chat trying to get this Wi-Fi calling sorted. They even sent me a new eSIM but that did not cure the problem.Spent most of yesterday afternoon on chat trying to get this Wi-Fi calling sorted. They even sent me a new eSIM but that did not cure the problem.I’ve confirmed with them that this problem also occurs on different routers and networks so they can’t blame that all this happened after the Carrier update, but typical Three deny all responsibility.

Or you could hope is that some of the tech guys also use Wi-Fi calling at Three as that’s the only way it will get sorted if it affects them.

As a long standing customer I’m inclined to agree with your last paragraph.

Sorry I'm not very familiar with iPhone settings, but does the Carrier update has a version number? And what is it? and what was previously?

Re: Wifi Calling not working on on of two phones on contract

It’s Three 64.1! Not something I particularly look at on a day to day so can’t answer the second part of your question but it’s absolutely too much of a coincidence that WiFi calling has become unavailable for some people following the update.

Thanks. I agree it's too much of a coincidence.

@Aircub128 @Midorie what is/was your version of carrier settings?

I always understood the WiFi calling being controlled by the phone itself not so much from/by the network. I also don't know wether the carrier settings influence or control the WiFi calling? and I was not sure who develops/creates the carrier settings but it looks like in the UK it is the Carrier or network operator/provider, so Three.

@Aircub128 @Midorie check this other thread here

Aparently from the idMobile community link that @Geluk posted, Three and Apple are aware and working on resolving the issue. I quote
"17:00 - 3UK technical teams continue to with Apple to work on resolving the issue. Thank you for your continued patience, and we’ll continue to keep you updated."

Hi everyone,

Thanks for your patience, and I'm sorry for the disruption this must be causing. We're working closely with Apple to determine the cause of the issue with the carrier update, so hopefully it should be resolved soon.

Thanks,
Jonathan

Yes, the iPhones support Wi-Fi calling as a basic function of the hardware/software, but the network provider also has to make the service available. Some networks for instance don’t offer Wi-Fi calling as part of a PAYG contract. That’s why I use Three - they do offer it on PAYG sims.

Hi Jonathan. Could you get your social media team to publicise there’s a fault on the Three social Channels? Also there was nothing about this on network status checker an hour ago. And I’ve had no direct communication from Three, a communications company, that this issue exists. Instead I wasted most of yesterday trying to get some sense from your business customer service team, who just tied me up in security questions. Clueless. Technical problems happen. It’s life, but it’s also when you discover how good the customer care is. Three business has scored a big fat zero. Currently with no mobile signal, no wireless calling. Dead in the water.

I have the issue after foolishly accepting the 64.1 update yesterday on an 18.5 iOS iPhone. What was I thinking??
