So I got a text message from Fido today that my phone (LG G4 on Marshmallow) now comes with wi-fi calling. I followed the steps to set that up, but everytime I get to the point where I click the link to register, I get a contradicting message that states that my device is not eligible??? I’m trying to do this over corporate wi-fi, could that be causing a problem?
Were you able to get the connection set-up for your Wi-Fi calling?
Let us know if you're still having issues and I'll send you a PM so we can take a closer look together.
