Department Data Locations Europe Remote status Fully Remote About Holafly During a trip to Thailand, Pedro and Lidia, the founders of Holafly, experienced the frustration of not having an internet connection. Inspired by their own experiences, they came up with a simple but brilliant idea: why not allow travellers to buy data plans for any destination from their home country? Our passion for providing easy and convenient connectivity to travellers around the world drives everything we do. We love our work and we do it with pride. Stay connected wherever you go.
