WiFi and 4G calling, O2 firmware

My samsung s8 plus doesn't seem to support Wifi and 4G calling,  I think this might be because I dont have O2 firmware.  How do I get O2 firmware?

Re: WiFi and 4G calling, O2 firmware

S8 will work fine on generic UK firmware too.
Make sure you have enabled it in your MyO2 and follow the setup process here https://www.o2.co.uk/help/network-coverage-and-international/wifi-and-4g-calling#samsung-setup

Re: WiFi and 4G calling, O2 firmware

I had a "chat" with an O2 "guru" a couple of days ago, and he claimed to have enabled WiFI and 4G calling on my account.  However, nothing has changed.

 

More specifically, I dont have either:

 

Settings > Connections > Wi-Fi calling

or:

Settings > Connections > Mobile networks > 4G calling

 

options in my menus, as described in the article linked by MI5.

 

So no, I've got nowhere so far.

Re: WiFi and 4G calling, O2 firmware

You can get any Samsung firmware here https://www.sammobile.com/firmwares/ Take care though as you can brick your phone if you make a mistake.

I have an S9 on O2 from CPH & because of that CS always try to blag me off that's why 4G & WiFi Calling causes me problems because I don't have O2 firmware even though O2's FAQ says you don't need O2 firmware on the S9 & I even flashed the O2 firmware for the S9 onto my phone & it didn't fix things one bit.

Currently WiFi Calling only works if I'm connected to WiFi & there's no O2 signal at all & 4G calling was working but not since today. All my calls are now going over 3G.

CS were obstructive, unknowledable & unhelpful.

I'm just curious is 4G calling working for anyone at the moment?

Re: WiFi and 4G calling, O2 firmware

Mine's working when I'm in an enabled area, but I'm not right now, so can't check it at this very minute.

Re: WiFi and 4G calling, O2 firmware

Well I've finally got it working.

A second "chat" with an O2 "guru" resulted in the conclusion thati did in fact need the O2 branded firmware.

I've was pointed at the sammobile site, which has to be the worst designed website I've ever been on. However, I did manage to eventually find and download the latest O2 firmware, and the uploading software as well.

Surprisingly, the re-flashing went smoothly and I still had all my data and apps. However, there was still no sign of the enabling options in the menus!

A third chat with the gurus went over the same old ground again, but then suddenly in the middle of the chat the options to enable wifi and 4g calling appeared!

I don't know whether this was coincidence, and it takes a good few hours for the features to filter through, or whether the guru did something to my account that he wasn't admitting to.

Anyway, b it looks like it's working now, the bottom line for me at least was:
I need to have O2 firmware on my S8+
Make sure the features are enabled on my account.
Wait fora day or so!

Re: WiFi and 4G calling, O2 firmware

My 4G Calling came back towards the end of last week. I guess it wasn't 'something you don't really need' as advised by CS :-p
