Hi,
Like many of you have said, we NEED Wi-Fi Calling because we cannot get mobile coverage where we live and likewise the internet itself was a 'bit' of a mission. We went from dial-up to ADSL and then managed to finally get 4G LTE, but the delay on the 4G was still not very useable for streaming TV - buffering constantly... However, through thick and thin, Wi-Fi Calling held its head high and kept up every step of the way - never once having any problems over many years of use.
Different mobiles, different operating systems and even different ISPs - no problems, ever.
We finally decided enough was enough and enough was too much, when Starlink became a cost effective option in our area - we dumped the 4G LTE and for literally a few dollars more per month we went from less than 30Mb (and ridiculous latency (triple digit)) to >300MB and all but no latency - no more buffering!
Oh darn, problems with Wi-Fi Calling - now what has changed? Updates to mobiles maybe? Surely, the amazing and fantastic new internet we have can't be the problem? Or maybe, just maybe it could be?
Remember - during "all of the above", we were using local devices to connect to our local Wi-Fi Calling service via our local mobile provider.
With so many different providers all connected simultaneously - from who you're getting internet from, to who your mobile is connected to - it can be difficult to determine where the cause of the problem is actually coming from. Then you throw into the mix all of the different makes and models of phones - plus the operating systems being used and their versions... The lions, the tigers, the bears - oh my!
We would get home, connect to the Wi-Fi, searching... No Service. Airplane Mode, nah. Off/on, sometimes. Change between 2.4 and 5Ghz, sometimes... Yeah/Nah.
We searched online forums and just found people asking for help - fair enough, occasionally people would take the time to provide basic troubleshooting links.
Does this sound familiar to you?
Then, one sentence in another forum made me try something that I hadn't thought of:
E.g. Wi-Fi calling will not work if the device is connected to a U.S based IP address...
I changed to the 'Custom DNS' in the App and put in the DNS addresses for the company that provides our mobile plan - poof, problems gone 🙂
Note: A lot of mobile operators now also provide broadband as well and separately. I specifically used the mobile DNS addresses of our provider.
We use iPhones, but they are not the latest and greatest and they both use a different version of the iOS - otherwise pretty standard stuff and it was only the Wi-Fi Calling that was having issues. Starlink is a great piece of kit and is proving to be the best choice we have made to date, except for a small hiccup lol.
Maybe this will work for you too? Good Luck!
