Me and my wife phones in Mississauga, Ontario were down for more than a day. There was no signal at all showing on our phones and could not text and make call.
Yesterday I went to Georgetown and all my phones worked again. When I came back at night, the phones were all working. Could not find the reason why, But everything is back to normal now with service.
There is simply no mobile signal shown on my andriod phone and my wife Apple phone screen. I am thinking some transmission tower or device were down in our area.
