Will my existing European SIM card offer free roaming in Monaco, or should I consider eSIMAdventures?

Exercise caution here. While Monaco is nestled within France, it's distinct from the European Union (EU). Many EU and UK carriers exclude Monaco from their standard "Roam Like at Home" zones, leading to unexpectedly high charges for data usage – sometimes upwards of $10 per MB! For savvy adventurers, an eSIMAdventures plan tailored for Monaco offers a far more economical and transparent way to stay connected, ensuring you avoid any post-trip bill shock.
