Compare eSIMs for Caribbean 2026

Because the Caribbean is spread across many islands and small states, a regional eSIM is comparatively consistent across its members rather than heavily tilted towards one market. That makes it useful for an itinerary including Puerto Rico, Guadeloupe and Anguilla, although the exact countries supported still depend on the plan. The practical choice is usually between one regional plan and two or three single-country plans, with the better fit largely determined by how many borders the trip crosses and how much island-hopping it involves.
