Answered question
My phone works normal now. What I did is that 1) turn off the Cellular Selection Automatic, wait until the Network list comes out; 2) If you see Videotron on the list, select it; 3) turon on the Cellular Selection Automatic, it now switch to Fizz, and everything is normal. If you can not see Videotron the list, try on and off again; otherwise, it won't work. My iphone works now, but my Android phone can find find the videotron, so it is dead still.
Try it. It may work for you as well.
I am thinking is the problem is because something happen on Videotron/Fizz?
