EuropaSIM
I have no experience of a WiFi booster, but I have of the company selling these ones, Motorhome WiFi. They are genuine and very helpful I have found. I bought a MiFi device from them and a SIM which provides data all over Europe. This is to give me an internet connection when there is no WiFi. I had a few questions about setting it up and they were very prompt to answer them.
