It’s hard to believe that a true prepaid mobile data SIM doesn’t exist in the USA, but it’s true. A GoPhone, H2O, or Net10 SIM isn’t a bad idea for your smartphone, but it’s not exactly cheap. The best option for those needing just mobile data is a local Virgin Mobile hotspot or a brand new Android phone or iPad!

What’s the Difference Between a Jailbroken and an Unlocked Phone?
If you’ve traveled much, you’ve probably run across “unlocked†mobile phones and devices. If you own an Android or iPhone smart phone, you probably also heard about “jailbreakingâ€. It seems like lots of people are confused about these two things, so I decided to write down a quick post explaining them.
Hands-On Review: Clear WiMAX Service (and PXU1900 USB Modem)
I know lots of folks who are happy with Clear or Sprint WiMAX service, and I applaud them for their no-contract Day Pass option. In fact, I wouldn’t hesitate to suggest that others go the same route I did: Buy a Clear modem on eBay and pay $10 per day whenever you need connectivity. But I strongly discourage readers from signing up for a long-term contract with Clear. Sprint subscribers will likely be upgraded to LTE eventually, but the future of Clear is very, very cloudy.
4G Connectivity Options Proliferate
I set out to find a faster mobile broadband service than the AT&T and Sprint/Virgin service I currently use. But exploring the world of LTE and WiMAX was a real eye-opener. I didn’t purchase a device (two, actually), but discussion of those will have to wait for my next post.
Building a Combination 3G/4G/Wired Wi-Fi Network
The Tech Field Day events I run are hotspots of social media, but it has been hard building an Internet presence to keep up. Constantly on the move, I need a flexible network with scalability and failover (and fail-back) between 3G/4G and wired Internet. My latest design relies on CradlePoint’s MBR1200 “Failover Router”, which can load-balance across multiple 3G and 4G data cards.
