Hi all,

I'm traveling to Canada for about a month for work, and I'll be hopping from province to province while I'm there. A friend is generously loaning me an unlocked iPhone that runs on GSM and accepts SIM cards, so I'd like to find someone I can purchase either a single months' worth of time from, or a pre-determined dollar amount that provides a given number of voice minutes and texts - preferably something with calling to the US included.

Where should I be looking? Thank you!
