Well that's even more of a mystery. I was not in the US or even close to a border that the roaming could have crossed over. I was home then at work for 9hrs in Stratford Ontario on June 3. I have been reading lots of Q & A on the forum and this seems to happen a lot to others. These extra "DATA" charges that people don't understand why they are getting them. Maybe something KOODO can look into.
Thanks for your reply. The $5 was paid. BUT I will sure be watching my bill very closely from now on.
