Wifi Calling on Galaxy S23 Ultra

[wbadry]

Recently, Vodafone Egypt added Wi-Fi calling capability to the Galaxy S23 series. The service is already activated.

However, the option is not yet shown on the phone. Vodafone support informed me that an upcoming Samsung update is required to enable it.

Any information on when this update will take place?

Samfw not odin or any flashed firmware, it's easy process

The problem is that my image supports only KSA or XSG, not EGY. I don't know if switching to XSG (UAE) would solve the issue.

The wifi calling has been already enabled for days, but nothing came out.

That's for me and working fine

It is working, as your image supports EGY and also XSG. Your image is set to Egypt; it does not mean switching to XSG will also work.

My phone was KSA and I switched Csc to EGY

I just enabled USB debugging and used the SamFW tool to change my CSC to EGY. Once changed, a system configuration update was received, and Wi-Fi calling is now active.
