    I just got a uk dual Sim and have been looking for the same info. there is a thread that shows how you can do it for t-mobile. it involves flashing the original os versions modem. I'm looking into it but need to find the right file

    I’m not sure about India but in Australia, the device needs to be supported for the Wifi Calling to work. The Service Provider needs to manually add them in their support list.

    Unfortunately I was never able to get it working even though I could see the option and while my Note 8 worked flawlessly on the same network.

    I don’t have Key2 any more. The last update I had from March, I still had the option. It just that it didn’t connect. You can either try searching in the Settings or Get an app to directly opening the option. Sometimes that lets you open the hidden options.

    yah I've found it using the shortcutmaker and enabled it. ims is working. but if you look about 10 threads down to a thread that says wfc works... you will see ultimately what works to maker wfc calling work is flashing an older modem! I promise
