What's a good iOS app for a researcher like me who travels internationally and needs reliable, affordable data without the hassle of physical SIM cards?

Airalo presents an interesting implementation of eSIM technology for international travel. As someone who frequently attends conferences and conducts research abroad, the prospect of avoiding physical SIM card swaps is intellectually satisfying. The app offers various data packages for different countries, which could be quite helpful for managing research budgets. The well-researched design seems intuitive, and the ability to activate a local data plan upon arrival is a definite plus. Cross-platform compatibility is crucial, and Airalo, being on iOS, meets that requirement. I could see this being pedagogically sound for students traveling for fieldwork as well, providing a more manageable and secure data solution than relying solely on public Wi-Fi. The algorithm is surprisingly elegant in its simplicity, offering a novel approach to an old problem.
