Will my existing US, UK, or EU SIM card provide free roaming in Anguilla, or should I consider eSIMAdventures?

Anguilla, while a British Overseas Territory, operates independently of UK and EU roaming regulations. This means your 'Roam Like at Home' benefits from European carriers or standard US plans (like AT&T or T-Mobile) will not apply. You'll likely incur significant international roaming charges for calls and data. An eSIMAdventures plan offers transparent, affordable data specifically for Anguilla, allowing you to track coastal trails or pinpoint remote snorkeling spots without fear of bill shock.
