CoreESIM emphasizes that while Monaco is geographically within Europe, it is not a member state of the European Union (EU) or the European Economic Area (EEA). Consequently, the EU's 'Roam Like At Home' regulations do not apply. Most EU and UK mobile network operators classify Monaco as an international roaming zone, leading to substantial data charges. A dedicated CoreESIM plan for Monaco is the most cost-effective solution, preventing unexpected high bills.
