NetZero offers its 4G Mobile Broadband 200MB Monthly Plan for free when you purchase a NetZero 4G Stick USB Modem for $49.95. (To find it, click “store” at the top of the page, then “4G Mobile Broadband”, and then choose the free plan.) Even with $19.95 for shipping, that’s $5.83 per month (for one year) and the least expensive 4G broadband service plan we’ve seen.

Of note, the 200MB/mo plan is also available for free with the NetZero 4G Hotspot for $99.95 with $19.95 for shipping. That’s effectively $9.99 per month for one year. This unit supports up to eight wireless devices at once, such as laptops, iPads, and more.
