Summary: This is a fantastic product. If you travel a lot and don't have data roaming on your phone, buy this. Basically, every place I travel to, I just go into the one of the local cell service providers, and buy a sim card with data.
Summary: Just returned from Sweden, Estonia, and the Netherlands. This device worked flawlessly everywhere. I purchased a SIM card before leaving home in San Francisco from a French company roaimg-one.com.
Summary: I'm deployed, I heard about this and was so excited to get it. I see my name on the package list board and can't wait to get a hold of my family, finally!!! When I open the package its a tablet cover with a charger, for a tablet I don't even have. Perfect.
Summary: I ordered the Huawei E5331 Mobile WiFi hotspot to use in Costa Rica, based upon one of the answers to a question whether it would work in Costa Rica. I set it up in the US, and even tested it with a T-Mobile Sim card before going.
