About a year ago I bought myself a wifi extender. My house, though not large, is large enough that the router doesn't give full signal in all rooms. With this router you plug it in a socket in the same room as the main router and connect to it using either Computer, mobile or pad. It asks for your routers key. Once entered it acquires your IP address and your in. You can then move the extender to a more central location to give better coverage. The other day at work, between orders, our mobiles wouldn't connect to the normal 3g - 4g network. We are allowed to connect through the works wifi. Well on the shop floor the signal from their router is poor but manageable. I took my extender into work and plugged it in. I was able to connect to the net under my IP address. No one else could, as they didn't have my routers password. I contacted the makers of the extender and asked, If I take my extender to another place does the extender act as a mobile router and therefore connects through the nearest router. Also does it use my account or the person who's router it is. Their reply was, yes the extender will connect through any router. Once it has been paired with my main router it obtains all its details and becomes a mobile router. Any charges would be billed to my router at home and therefore no charge would be incurred by the owner of the router it was using to piggy-back its way to the net. I have unlimited internet on my router so would not be charged any more than my usual monthly tariff. So in theory if I was to go on holiday in this country I could take my extender with me and use it as a mobile router (as long as there was a main router near by to connect through (apparently this other router doesn't even have to be open or signed into, as long as it's turned on, I'm in) My mate is going to try this when he goes on holiday to south Wales in a coupe of weeks. We shall see.
