Connectivity overseas can be a real pain. Roaming is prohibitively expensive, so a local SIM is best. But most American mobile phones are “locked” to a carrier, and American phone companies use different network technologies and frequencies than most other countries. That’s why I was excited to test my Verizon iPhone 5 abroad.
Is there no such thing as a cheap, prepaid data SIM in the USA?
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!
Making Sense of Global Mobile Phone Networks
The mobile phone network landscape is incredible confusing. I pulled together the following overview to help myself make sense of it, and I thought it might benefit my readers, too.
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.
Which iPad is the Best Choice?
Apple may make their product lines easy to understand, with simple and consistent names, but there sure are a lot of iPad 2 models. Which iPad is the best choice? I picked the 32 GB Wi-Fi model personally, but I can see cases where others might prefer a 3G or base model. Let’s consider it.
