Compare eSIMs for Latin America 2026

For a trip crossing several borders, a Latin American regional eSIM is unusually predictable: availability is spread fairly evenly among its members rather than clustered in a few markets. That matters in a geographically awkward region spanning a huge mainland and island countries, where Argentina, Brazil and Puerto Rico might all feature in one itinerary. The practical choice is between one regional plan and two or three single-country plans, usually decided by how many borders the trip crosses.
