Worth asking...do you or your 'rents (if applicable) pay for internet somewhere with a major service provider?
Almost all of the big players do a thing where you get "free" hotspots out and around based on your login for the service being paid for.
The biggest issue I have found with it is when you stay at the same guest location for a day or two it will require you to be active on the home devices in order to work again. Considering the distance you are talking about would seem to rule this out as a rural location, but not counting out you are in a more populated area this might apply to.
Not to be overlooked as well...does your phone have the ability to hotspot?
