A little unit which exceeded my expectations. It is smaller than a mobile phone and neatly designed. It comes with a 20-page colour printed quick start guide (which clearly states on page 4 that the antenna port requires a TS-9 connector). This guide is enough to get you up and running, but if you need further information there is an even more comprehensive set of instructions embedded in the on-board Help system which you can access through a connected Wi-Fi device or computer.
Connecting wirelessly with my laptop and smartphone was a breeze - just as easy as logging on to a secure WiFi signal in a café. I had a little more difficulty when I tried establishing a wired connection via USB, but I put that down to my lack of experience with Windows networking rather than any shortcomings in the Mobile Wi-Fi.
I bought a Spanish SIM on eBay which enabled me to email, surf the net, watch online videos and make video calls on holiday, picking up an excellent 3G signal without the need for an external antenna.
