This review is from: Huawei E5331 High Speed 3G 21.1Mbps Mi-Fi Unlocked Modem (Electronics)
Ideal if you have more than one tablet/laptop and only one data sim you wish to use. It also means you can have wifi-only systems which are cheaper to buy than the 3G units. I've used the 3G data sim from Amazon with it and it works easily.
