Cheapest eSIM for the Caribbean

What the cheapest Caribbean eSIM costs right now

As of 1 September 2026, 23:15 GMT, the best value Caribbean plan is MobiMatter at $19.99 for 25 GB over 30 Days. It covers 3 countries on one eSIM, so you install once and keep the same line as you cross borders.

A multi country plan is rarely the cheapest way to cover a single destination. It wins when you are visiting several, because one install replaces buying, installing and switching between separate eSIMs at every border. Compare the per GB figure here against the single country page for your main stop before you decide.

Which countries these plans cover

Coverage varies plan by plan. These 44 destinations appear in at least one Caribbean plan we track. Always check the individual plan before buying, because none of them cover every country on this list.

Is a Caribbean plan worth it?

Buy one when your trip crosses borders and you would otherwise juggle several eSIMs, or when you want one line that keeps working the moment you land somewhere new. Buy a single country plan instead when you are staying put, because the per GB rate is almost always lower.

Check three things before paying: whether the countries you actually need are on that plan's list, whether the allowance is a total or a daily fair use cap, and whether it can be topped up if you run out mid trip.
