The Novatel MiFi 2200 is a great device. It collects 3G signal from Virgin Mobile USA's network (a.k.a., Sprint), and creates a Wi-Fi hotspot that can be accessed by up to five other devices. It doesn't offer the sprightly WiMax-powered experience that the Sprint Overdrive does, but it trades raw speed for better budgetary options.
The device sells for $150 and can be used with Virgin's pre-paid Broadband2Go Web service. Users aren't charged activation fees. Data can be added to the Broadband2Go Top-Up cards for the low price of just $10. The plans are the same as Virgin Mobile's other pre-paid data plans.
The lowest plan costs $10, and that buys 100MB of data, which expires in 10 days. Virgin Mobile says 100MB is good for about five hours of Web browsing. For $20, users will get 300MB, which is good for 15 hours of browsing. The 300MB also expires in 30 days. For $40, step it up to 1GB, and $60 buys 5GB -- each expiring after 30 days. So if you pay $40 for 1GB and only use 500MB, you lose access to that unused 500MB. For reference, Virgin Mobile says that 5B of data allows for a whopping 250 hours of browsing time. That's way beyond a 40-hour work week for an entire month.
