Wifi calling

[MatthewJo]

I am a user of Samsung galaxy note 8.

I don't see wifi calling on the phone setting after changing a carrier.

You need to reset the phone to change the CSC code and it might appear.

I did reset two times. Not working.

Resetting Network Settings / Factory Reset won't ever change the CSC.

Flashing the CSC will, but just inserting the new Carrier's SIM should allow WiFi Calling, if the Carrier has it enabled for the device.

But if the device is a International Exynos variant, or a U/U1 US model, then it's not going to work.

Sorry my mistake. He has to use the dialer to change the CSC code which will then automatically reset the device. If you check my posts, I had to do it a few times before when I changed carriers. It doesn't enable VoLTE and WiFi Calling if he doesn't change the CSC. That's how the Note8 works probably because it's an older device?
