I am trying to activate Wi-Fi calling on my S7. The phone was not purchased via the carrier, however I have taken the steps to flash the phone with the latest stock firmware and it is now using the unbranded CSC code BTU. I thought that would be enough to activate based on some of the comments I’ve read here but it seems not.
If anyone has this working with an S7 or any similar Samsung S8/9/10 etc I would be grateful if you could do two things:
Check current firmware by typing *#1234# into the dallier
Go to the play store and get the app Phone INFO *SAM* - then scroll to the ‘CSC Code’ tab and check the Active CSC code. Mine is currently BTU

Thank you for your patience whilst we investigated the WiFi calling issue for you.
Unfortunately we are unable to have the WiFi calling feature working on the device that you have purchased. This is due to the fact that the device has not been purchased from ourselves directly and we can't guarantee that the feature will be compatible with devices purchased elsewhere.
