It's a common misconception, but unfortunately, no! This is a frequent roaming trap for travelers to the Caribbean. Even though Sint Maarten is part of the Kingdom of the Netherlands and Saint-Martin is French, neither side is considered part of the EU for roaming purposes. Your 'Roam Like at Home' plan from carriers like KPN or Orange won't apply, and you'll face hefty international roaming charges. SouthESIM offers a much more budget-friendly and transparent way to stay connected across the entire island.
