eSIM for Caribbean
One data package for the whole trip. The Caribbean plan covers 24 countries — check the list once and stop thinking about borders.
Choose your plan
Every plan below covers the same 24 countries with one shared data allowance.
The allowance is shared across all included countries — it does not reset per country or at borders.

24 countries on one package. A few of them:
- Included countries
- One data allowance for the whole package — use it in any mix of the 24 included countries. It is not per country.
- When validity starts
- Your package starts when your phone first connects to a network at the destination — not when you install it. Crossing a border does not restart it.
- Entering another included country
- Your phone picks up a partner network in the new country automatically — keep data roaming on for the onesim line. No settings to change and nothing to reinstall.
- Outside the covered countries
- The package does not connect. Your phone falls back to Wi-Fi or your home SIM if you allow it — check the list before you go, and look at another onesim package for uncovered stops.
- Calls and texts
- onesim is data-only. Calls and messages work over data in apps like WhatsApp or FaceTime; your usual SIM keeps your number.
- Support and refunds
- Message the onesim support team from the app or the website. If a package cannot be installed or used, the refund policy explains what applies. Refund policy
Caribbean plan questions.
Answers for trips across more than one country.
Open “See covered countries” and search each stop. The list is the authoritative source: if a country is on it, this package works there; if it is not, we point you to another onesim package if one covers it.
No. Validity runs from your first connection in any included country and continues for the plan’s full duration wherever you are on the list.
The package will not connect there. Check whether another onesim package covers that stop, or plan on Wi-Fi for it.
Yes. Your account has one onesim eSIM, and you refill it with any regional package from anywhere in the world — from the website or the app. The new package is added to the eSIM already on your phone; there is nothing to install again.
