Will my Dutch (KPN) or French (Orange) SIM card allow free roaming in Sint Maarten?

Sint Maarten is not part of the European Union. Consequently, your Dutch “Roam Like at Home” (RLAH) plan from carriers like KPN will not apply, leading to high international roaming charges. Similarly, for French SIM cards (e.g., Orange France), while Saint-Martin is an overseas collectivity of France, it is outside the EU roaming zone, and standard EU RLAH rules do not extend there either. Both scenarios typically result in expensive out-of-bundle rates. A CoreESIM plan designed for the Caribbean ensures predictable and lower data costs.
