abroadband: Data Access for Travellers
My friend Rafe Blanford pointed out this service, which I hadn't heard of until now. It looks interesting - at current rates, it's about 86 cents USD/CAD per MB, and they support SIMs, microSIMs, and USB sticks. That's not "I'm going to order a TV season on iTunes and download it all" cheap, but if you were careful about not downloading email attachments and were sparing with your Internet access, you could make a $40 investment last a week or two. While you can check your online balance easily, it seems this isn't a true pre-pay solution...the metre keeps running without stopping, so be careful what you decide to download.
Note that this is for data only: this is for your laptop, tablet, or I-only-want-Internet-phone. If you want to use your phone abroad and do voice calls, text, etc. you'll need to get a SIM from a wireless carrier. Anyone know of a service similar to this but for full phone service?
