WiFi calling on non O2 phones

[Redrooster]

Have moved house and reception inside is non existent so need to upgrade to a phone with WiFi calling.

I'v been looking at the Samsung A50 but do I need to buy it from o2 for the WiFi calling to work or can I buy elsewhere as long as it is UK version.

Your help is much appreciated.

As far as I am aware Wifi Calling only works on phones which have O2 firmware installed.

That was the situation 18 months ago, see here https://community.o2.co.uk/t5/Business-Customers/WIFI-Calling/td-p/1163249 

Unless it's changed since then and I am unaware?

*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.

@Redrooster  As the A50 is asterix free, then that should be ok. Thanks for that update @MI5

You're welcome

Thanks for the replies folks. Seems I can get it cheaper elsewhere so should save me a few quid.
