Wi-Fi calling no longer working on macOS Sequoia 15.5 and 15.6

Resolved in my situation. At Apple's suggestion that my cellular provider had to enable wifi calling, I just got of a 1.5 hour call. Before getting too into the details (we checked all related settings), first —

• on your iphone, turn on Airplane mode to disable wifi, cellular, etc.
• on your mac, open facetime and attempt a phone call
• the call processed on the mac as per normal experience
• the macOS still showed the "waiting for wifi calling activation" message
• remember to turn off Airplane mode...

My assumption given everything we did is that the facetime software has preference for a cellular connection that it tries first and if it is available, it will use the cellular path for the call handling ignoring the wifi path.

Steven Skorka, Thank you for writing this note as it helped point me to a resolution path.

macOS Sonoma 15.5 and 15.6 - WiFi calling no longer working

Over the past week or so, WiFi calling on my MacBook Air (M4; macOS 15.5 and 15.6) no longer works. When I try to re-enable it, nothing happens. I can still make phone calls from my iPhone on my Mac when the phone is nearby, but can no longer do so via WiFi without the iPhone nearby. WiFi calling has been working well for years.

Looking for any ideas/suggestions. Thank you.

Steve

Just tested the process on second (ipad w/cellular) and third (iphone) devices. Worked as well. Forgot to disclose that we have t-mobile service which include wifi calling in our package. Advice, if this test does not work, then do call your cellular provider.

Shame on Apple for blaming this on the mobile service providers. The agent I spoke with is submitting the procedure of checking their services as I write this. She was very patient.

I thought a bit more about this. The use case that Apple Facetime seems to have implemented in 15.6 is one that assumes cellular is available from the iphone until it is not; then and only then, does the mac switch to wifi calling. What made me re-think this is I have some places that I travel to regularly that have poor to no cellular service. In one of the poor cellular service locations, the fix was to do exactly what resolved it this time, i.e., essentially disable cellular, then the wifi call worked.

Do you have a different use case? Because the irritating thing perhaps is that it seems one cannot choose to use wifi only. I may be wrong, but I thought that in the past I was able to not worry about the phone, but was able to use the laptop to make wifi calls.

Any updates on this. I have tried just about every remedy someone is suggesting on the internet, with extremes like logging out of iCloud and back in, nothing will get the "Upgrade to WiFi- Calling to stick. The funny part is that it does work on my iPad just fine. If I disable my phone and try a call on my iPad it goes through, just not my MacBooks.

majorgearhead, it sounds like you've already worked through the testing that I wrote up in the Aug 8, 2025 02:45 PM in response to Steven Skorka, i.e., I'm reading your note's "disable" as turning on airplane mode. Sounds like there may be other problems with Apple, especially since you are seeing it work on your ipad and not your macs.

Sorry for the multiple messages. Please make sure your devices are already updated to macOS 15.6, iOS 18.6, ipadOS 18.6, etc., to save yourself some call time.
