Connectivity overseas can be a real pain. Roaming is prohibitively expensive, so a local SIM is best.

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.

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.
