WiFi and 4G calling on new mobiles

[Bychan1970]

Good evening

My Oppo Find X3 Lite has now reached end of life support wise, and both WiFi and 4G calling work fine on it, on an O2 pay monthly SIM.

If I were to replace the mobile with one of a Poco X6 Pro, Redmi Note 13 Pro or a Samsung A55, is there any way to confirm that both of these features would work with the O2 SIM 🤔

I recall a list of supported mobiles on the O2 website, but that seems to have vanished some time ago.

Anyone using any of these with an O2 SIM 🤔

Any feedback appreciated.

Thanks

The golden rule is that any phone that O2 sell is supported (does not have to come from O2, just the same as they sell).

Anything else may work, but not guaranteed and no support will be available in case of issues.

Therefore, you are safe with the Samsung A55

Thanks 👍

This was where the list of supported mobiles used to be, long gone.

Makes sense in that mobiles supplied by O2 would be supported, even if not bought from them. This was the case with my Oppo a few years ago.

Shame they no longer provide a list of supported mobiles, as they did previously.

Thanks 👍

I bought the A55 direct from Samsung and can confirm 4G and WiFi calling work perfectly on O2 and the EE sim in the other sim slot. Also worked fine with a Thai sim too....
