4G Pack 2 & iBoost
Purchased and used Motorhome WiFi equipment since Adam & Sophie first started. To my mind any extra cost is cheap at the price considering the help and support they give. in pre WiFi days I found it invaluable in connecting to FOB when it could be found, which was more often than some people may suggest, and these days for example, the WiFi booster greatly speeds up the connection at CampingCar Parks for example.
The roof mounted 4G aerial and modem makes it seem like being connected to our home wifi most of the time, both moving and statioary, and sometimes enables a wifi signal even when the phone doesn't.
