How to manage phone data across multiple countries
Online advice for international phone plans is deeply confusing, and eSIMs often fail to work as expected. Overpriced options in low-cost countries make it especially hard to figure out a reliable setup when jumping between borders. The process is so frustrating that many travelers simply skip getting data altogether for short stays.
