I went to Las Vegas recently and used Roam instead of Telus's plans. I have to say it worked flawlessly. Data, text and even telephony. I used it in Detroit also and it worked great there too. This is an awesome option for Canadians traveling to the US and needing a data plan on the cheap.

Anyway, this forum seems to be pretty dead so I thought I would chime in with up to date experiences.
