That's pretty bad news, the 4G and 3G signal used for phone calls is pretty weak in my home and work area, had many issues mostly solved when I upgraded to my S7 with VoLTE.
I came from Videotron, but I didn't know about their VoLTE policy for BYOD.
However, it shouldn't be a technically issue for Fizz exactly because Videotron run them and they have it implemented since a year ago.
On the other hand, with so many issues on basic services like SMS and voicemail, probably yes, I'm dreaming they even just look at this now.
