Founders František and Jan experienced problems with mobile data every time they traveled outside the EU. As technology enthusiasts, the idea of traveling abroad without a data connection or risking truly insane roaming fees was unacceptable to them. Regardless of how adventurous the story of walking across Toronto on a winter night without an online map might be, it's not something they would want to repeat.
After the emergence of eSIM and later eSIM travel data package providers, they learned a lot about the technology and industry and decided to share their findings and the comparison tool they created for themselves with others. It now contains more than 10,000 updated eSIM mobile data packages from the most popular providers for more than 170 countries around the world.
