Travel to Canada

I was just in Ontario for the last two days in the Brockville area right along the 401.  I had purchased the two days of extended international coverage.  Mainly for the data for my Maps and Facebook, etc.. The coverage on voice was good, but the data coverage was hideous.  I should’ve saved my money and just driven from Tim Hortons to Tim Hortons.  One of our iPhones was connected to “Bell” the other to “Telus” which was confusing.  It’s Canada for goodness sakes.  Figure this out already.
