WiFi and 4G calling, O2 firmware

ejfield — Fri, 07 Dec 2018 13:26:59 GMT

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?

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

Hi @ejfield, let us know how you get on with this - any help from the above advice from @MI5?

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.

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?

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.

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!

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 😛

Funnily enugh...

I had an instance where I recommended the same thing and had my post removed and requested not to post anything similar up again.

Cleoriff — Sun, 06 Jan 2019 19:42:45 GMT

Ridiculous really. The guide we had was on here for years. It gave all the warnings but was so easy to follow...

Now apparently it's ok for O2 to tell people how to do it?

I think the guide should be reinstated.

At least there are people on here who can help and advise. (Not me of course) but others can do it with 'their eyes closed' so to speak...

MI5 — Sun, 06 Jan 2019 19:44:09 GMT

The "reason" for it from O2 is that they were worried they would be responsible if someone bricked their phone, this, in spite of the fact that my guide was up for at least 5 years, had been viewed by thousands and not one single person had screwed up anything or sued O2 over it.
Yet, live chat, who barely know what day it is, can happily give out this advice ??

Exactly that @MI5.

You are correct, not one person claimed they had 'bricked' their phone.

It had a great response from people who used it. I know who I would trust with this and it wouldn't be Live Chat...

thankyou for posting this info ejfield. I too am trying to get wifi calling working on my S8, so far no luck but your post has given me hope that I could flash my phone with O2 firmware and get it working. one question though - how do you 'know' that you are making a wifi call? could you post a screenshot of what a wifi call looks like on an S8?

You'll know that WiFi calling is active @tonjg as there will be a symbol in the notification/status bar.
Mine looks like a phone with the WiFi symbol coming out of it.

MI5 — Thu, 01 Sep 2022 07:56:03 GMT

@tonjg

As posted previously, you need to put phone into airplane mode and turn on wifi.

If you can then make a call, it's working.

Thank you MI5 I tried what you said but the call didn't work I'm hoping that replacing the firmware will solve this
