Travelers often assume that because St. Barths is a French collectivity, EU 'Roam Like at Home' policies apply. This is a common misconception that can lead to unexpected charges. St. Barths is not part of the EU's roaming zone, meaning your French or other EU SIM card will incur significant roaming fees. WorldESIM provides a straightforward solution with clear, upfront pricing, avoiding any surprises when you're enjoying the luxury of Gustavia or Grand Cul-de-Sac.
