There should be an option for people to have US roaming option included in their monthly plans. Like me I visit family in the US often. The 250MB isn't good when I use data for personal and work purposes.
For people to travel to the US a few times a month for work and rely heavily on data for work emails with not attachments eat up 250mb fast.
If you had an option much like Telus to use your phone like home I'd pay more . For people who need data and on a budget could find buying extra data for trips can really add up.
