iPhone XS Not Compatible with Wi-Fi Calling

Hi Everyone,

Are there any clues as to why my iPhone XS is not compatible with Wi-Fi Calling and 4G Calling? They are enabled on the phone. IOS 13.0.

Not sure.

It seems to take some time to update apps, after installing iOS 13.

Presumably you have deciphered the means of updating apps?

Give it a day, or so, and perhaps you may try a Power Down / Restart. 

Don’t do a full reset!

@Ribblelancs  Unfortunately it has never worked. It worked fine on my iPhone 6S but stopped when I upgraded to XS. I have tried all the usual things, restart, disable, re-enabled  etc. but has been like this for approaching a year. All Apps are up to date.

Re: iPhone XS Not Compatible with Wi-Fi Calling

I’ve had problems since updating to iOS 13 on an iPhone 8 Plus.

Connection to the wifi Call seems to struggle for several 10s of seconds, before the notification appears.

Is your 4g signal strong? It’s difficult to get a precise measure of signal strength on an Apple device. You need an Android phone for that, with an Application.

Perhaps you don’t need WiFi calling in the home?

Give it a while, then I’ll ask for assistance from the Mods........There’s been a lot of work in promoting WiFi Calling.   And it’s still a bit confusing.

Re: iPhone XS Not Compatible with Wi-Fi Calling


The page for announcing this service - last updated 25th July 2019 says the following: 

What phones does Wi-Fi Calling work on?

To use Wi-Fi Calling you will need a compatible handset.

All iPhone models from the 5S onwards will be compatible. This includes the iPhone 6, iPhone 6 Plus, iPhone SE, iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus and iPhone X.

It says '5S onwards' but yet only lists up to the iPhone X. 

For some reason, it would seem incompatible - as this was last updated July of this year.

@albertj@VeteranISPUser ,

It will probably work on the iPhone XS.

After some fiddling here today, the mobile signal is strong so Wi-fi calling is not needed.

If you go to settings > data options, check that the Wi-fi calling option is there. If it isn’t, then you are stuck!

Here: - the Wi-fi setting is there, but the phone doesn’t connect.....only to data connection.

When it does connect, it can take up to a minute for the display to show it, presumably as the data signal strength varies. Once connected it remains connected to Wi-fi calling ( if you are stationary).

Somehow the phone used 1MB of data in deciding - or that’s what MyBt says......not much to complain about.

Interesting, it says BT WiFiCall (top left) on the notification screen but No and Not Compatible everywhere!
