Relying on your European (EU) SIM card for free roaming in St. Barths is a common oversight that can lead to unexpected charges. While St. Barths is a French collectivity, it is notably not part of the European Union for roaming purposes. This means your 'Roam Like at Home' benefits typically won't apply. Carriers like Orange FR will charge you international roaming rates. For predictable and cost-effective connectivity for your monthly stay, Truly Roaming offers dedicated plans that eliminate these surprise bills, providing reliable data for your work.
