*On some Android devices, Wifi and 4G Calling will only work if you’re using O2 firmware. That’s essentially the software that makes your device turn on and run. Sometimes there are different versions of firmware for the same device.

Is this still up to date? I have a Pixel 4A but can't seem to get WiFi calling to work with O2.

The Pixel 6 is missing and that works, so the list is a bit out of date.

Have you contacted O2 to turn WiFi Calling on your account as it's not enabled by default?

@DougDoug 

O2 no longer list individual phones for compatibility, they just state "all phones sold by O2 are compatible"

I have a Pixel 4a and I can't find selection calling.

I've had it before on Virgin and EE.

Can anyone help

Thanks

Have you contacted O2 to turn WiFi Calling on your account as it's not enabled by default? And it only applies to Contract and Business phones, WiFi calling not available to PAYG customers, @jasonbrown2507 

O2 are contactable on 202 or via Social media, links to which are in the page linked just below this post. Good luck!

Do you have to buy the phone from O2 for it to be compatible with Wi-Fi calling?

No, you do not - phones sold by O2 use standard firmware since 2018 or so, @Rob521 

You do have to be a contract or Business customer, as O2 do not offer Wifi Calling to their PAYG customers.
