Wi-fi calling on S9

Does anybody know if wi-fi calling is supported on S9 with OXM in the CSC code? I have had conflicting information on this so would be great to know if anybody has this working

Re: Wi-fi calling on S9

Yes, the S9 is compatible with O2 WiFi calling on either O2 or generic Samsung firmware.

Re: Wi-fi calling on S9

HI MI5,

 

You seem to be very knowledgeable on Samsung calling issues.

I am running an S9 with CSC: G960FOXM2BRJ3

 

On o2 I wish to use the wifi plus 4g calling feature. I have activated it using my02.

I can go to settings>mobile networks>VoLTE calls and toggle on fine.

I cannot find anywhere in the menus the WI-FI calling option.

 

Can I get this to work or do I need another firmware? 

 

Thanks

 

Vish.

Re: Wi-fi calling on S9

@vish28 it should work for both as they com together as a package.

Check in the phone app settings for wifi calling as Samsung keep moving the menus around.

Re: Wi-fi calling on S9

Thank you MI5, you are right!!!

 

The impossible menu has been located:

Settings Menu > APPS  > hit the 3 dots top right > Show system apps > scroll down to Phone (there's 3 of them), select the first one > tap the settings nut above 'force stop' > scroll down and you find Wi-Fi calling >

Toggle it on.

@vish28.
Know it was a few weeks ago, but how did you know 4G calling is working? Do you have an icon?

Thanks

Re: Wi-fi calling on S9

Yes, there is an icon.

To test it, put your phone in airplane mode, then turn on wifi.

 

See image link for the icon:

If all this is on, then try make a voice call.

I have found the wi-fi calling option is sometimes off after any android updates, so double check the hidden menu one is enabled first.
