@JollyRoger -- I even called my mobile from my home phone with the same result.
At that moment, could you call from your mobile to your home phone, or did you get "no service"? At that moment, was your mobile connected to the "Shaw" towers or to the "Nationwide" towers?
Saturday, I had an employee of "The Source" (formerly Circuit City, formerly Radio Shack) try to tell me that the "Nationwide" network is on the Freedom Mobile towers. Sigh. Looking at Shaw Mobile's "coverage map" map, I did not believe him. He wanted to sign me up with Bell Mobility. No thanks.
