I brought a Galaxy S25 Ultra from Korea and am using it with Visible. However, the option to enable Wi-Fi Calling does not appear in the Phone app settings. Could you please help me resolve this?

@drhell I'm going to guess that Visible isn't recognizing the device's complete capabilities because it is not a US model.

This is something I found on Google:
Wi-Fi Calling on Android is enabled by mobile carriers, not phone manufacturers. You'll need to check with your specific carrier to see if they offer and support Wi-Fi Calling, and if your phone model is compatible.

Qualcomm SoCs' carrier bundles are inside the modem config, which might be shrink for regional optimization. Try *#*#4636#*#* in your dialer and see if there's an "IWLAN" showing while turning on the airplane mode.
