S10 WiFi calling

[an-other]

I’m about to be given an s10 from work that is unlocked. I currently have an O2 sim only contract so was going to put the sim in from this.

Does anyone know if the WiFi calling will work? I’ve read lots of different things online and can’t seem to find a straight answer.

Any help would be greatly appreciated.

Yes, the S10 is supported and will work on O2.

Great. Thank you. Someone at o2 on the phone said it wouldn’t because it was unlocked but someone else said it would.

It will be on generic firmware I assume?

[an-other]

I’m not sure sorry. All I’ve been told is that it is unlocked and not assigned to an individual provider.

Ideally I'd need the CSC off the phone, but the S10 is definitely supported on either O2 or generic firmware.

@MI5 Thanks!

Would generic firmware be on a phone that is unlocked?

Yes, that would be standard firmware on a phone that was supplied unlocked by Samsung originally.
