Wi-Fi calling.

Mi O2 sim allows WiFi calling. How do I set this up on my Xperia X (F5121)?

TIA

This has been asked before, you will need O2 to release an update so you can use this feature. I'm not aware if this Xperia model has been available through O2, if it has then you could manually install the O2 firmware which should enable the feature, assuming that O2 has enabled such feature on this device.

Hi @10tus,

There are some other requirements that needs to be fulfilled even if your subscription supports Wi-Fi calling.

If the setting is available, you will find it if you open up the Phone application > tap the three dots in the top right corner > Settings > Calls > Wi-Fi calling.

If the option is not available, get in touch with your operator and make sure that they support Wi-Fi calling for your phone model and they will also know if the device needs to bought from O2 or not (if it needs a specific software customization).

I hope that helps!
