Decided to stay with O2 when upgraded phone to Glaxy A51 & wanted to be able to use WFI calling but is not working on, my 'phone's firmware is not compatable.  When will firmeware be upgraded so it is compatable?

Your phone does not require specific O2 firmware to use wifi calling.

Have you checked if your firmware is up to date?

Settings >About >Updates

Also, where did you get the phone, was it from O2 or a third party?

Phone purchased July 2020 via O2 online

Last software update 6 May 2021

How/Where do I find date of last firmware update

Dial *#1234# and check the CSC number.

Firmware - CSC: A515FOXM4EUCB

According to extract below from O2 site it would seem my phone is not supported?

According to O2 site device will need to use O2 firmware. Your device should use O2 firmware if you bought it direct from us in an O2 shop, online or over the phone.

To check if your phone’s running O2 firmware, dial *#1234# and look at the CSC entry. If this line includes ‘TEF’, ‘O2U’ or ‘OTF’ then your device has O2 firmware and you can set up Wifi and 4G Calling. 
If the CSC doesn't include one of these codes then Wifi and 4G Calling isn’t supported on your phone right now.

That only applies to specific phones but yours is not one of them as I said previously.

You have generic UK firmware but you're not up to date.

The latest for your phone is A515FOXM4EUD7

[Dressagediva]

Thanks.  How do I get latest version of firmware?

@Dressagediva 

Can I just check that CSC again?

A515FOXM4EUCB

or A515FOXM4EUC8 ?

If it's 8 you have somehow got Three UK firmware on your phone, which is why wifi calling isn't working, so you'll need to flash A515FOXM4EUD7 to get it to work.

I'm not allowed to tell you how to flash firware on here, sorry.

But you can find all you need, and do so at your own risk, here

the CSC entry is: A515FOXM4EUC8 

My apologies misread my own writing.

How do I get this version?
