Hotspot service for 1 day?

Looking for a way to have 1 day of mobile hotspot service while I'm on tour, so i can work from my computer on travel days in the tour van.

Looking at prepaid mobile hotspots. Is that the best way to go? I don't want monthly or annual contracts or service, just would like to pay for data usage on days I travel. I also don't want my data package to expire (like prepaid plans that mention a 30 day time limit)

thank you!
