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!
I simply cannot recommend any Eye-Fi card, even the fancy new X2 line, to average camera users. Even enthusiasts like me would be wise to curb their enthusiasm. Most features barely work in practice, and the device frequently failed to perform.
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.
I love my Cradlepoint PHS300 router. It’s been a constant companion for me for two years, providing Internet access for me and my friends at just about every conference I attend (and organize!) It’s a battery-powered box with a USB port and WiFi radio. Attach almost any 3G or 4G modem or smartphone (other than the iPhone) and you’re online and sharing. And it’s better than a MiFi: You can customize the experience, it’s faster (in my testing), and it scales to support way more users.
