This is really frustrating for temporary visitors (even us Americans that live abroad but visit on occasion.) Here I can pay about $3 for a SIM card and $1/day for a "data package", all prepaid, and most of the world has similar options available.<p>When visiting the US, I've tried using some of the cheaper, less known providers that they sell in Best Buy (H2GO, Boost) and have never actually gotten data to work, just voice. The only thing that has worked for me is T-Mobile, for which I have to fork out $50 for a month, when I just want 4-5 days.
