UNLOCKED Option iCON452 USB 2G 3G cheap Mobile Broadband SIM Dongle Internet
I tested it with EE and Giffgaff sim card. 2G and 3G dongle. - Unlocked for all networks (UK and overseas). If you live in area of the UK where 3G is switched OFF then this device will still work under 2G coverage, slow but better than nothing.
