As full-time digital nomads, we've used Airalo and Holafly extensively. Both Holalfy and Airalo are reputable eSIM providers, offering global coverage, fast mobile internet, and easy-to-use apps. Our review of Holafly vs. Airalo is not based on a couple of weeks of use on holiday, but from thorough testing of both eSIM providers for over a year, in some of the most remote places in and around Europe.
