Quick answer
If your trip takes in several islands, one global eSIM saves you buying and installing a plan for each stop. Airalo’s global eSIM covers every island on this site, from $8.50 for 1 GB over 7 days. Roamless sells pay-as-you-go credit that also works on every island and never expires; it charges each island’s own rate per GB. Going to just one island? A plan for that island is usually cheaper.

Common questions
Is a global eSIM cheaper than a plan per island?
Usually not. For one island, that island’s own plan costs less. A global eSIM is worth it when you visit several countries and don’t want to buy and install an eSIM for each.
Does a global eSIM work at sea on a cruise?
No. At sea your phone connects to the ship’s own network, which these plans don’t cover. See our Caribbean cruise eSIM guide.
Which network will I be on?
It depends on the island. Each plan uses a local partner network in each country; the island pages list the networks we know about.
