I'm planning a Europe-wide trip in a motorhome I've bought. I'd like to stream the trip from the front of the motorhome to YouTube, basically a live landscape with music. To do this I'm trying to overcome the technical hurdle of data usage throughout Europe.
At the moment, my super basic plan is to use a phone to stream from with a high-quality video image and buy individual pre-paid unlimited SIM cards in each country as I arrive (I'm currently with Three in England and they allow unlimited data within England, but only 12 GB per month tethered or roaming in Europe).
However my preferred option would to be use a Mobile Wifi (MiFi) dongle as then I can use a proper webcam/streaming camera connected to a desktop or laptop in the camper. I can't find an unlimited Europe-wide MiFi plan in the UK, but that doesn't mean a different country in Europe doesn't have a viable plan.
Does anyone know of which countries might have viable data plans?
