Horizon, Ubigi and Saily: compare the same allowance and validity
All prices below were displayed in EUR on 26 October 2026. No currency conversion, coupon, affiliate discount, subscription or future cashback is included. We compared the named regional products, not the providers' cheapest country offers.
| Regional eSIM | 1 GB / 7 days | 10 GB / 30 days | Coverage detail |
|---|---|---|---|
| Horizon Greater Caribbean | €3.09 | €21.19 | All 29 countries and territories listed above |
| Ubigi Caribbean | €7.00 | Not checked | The checked 1 GB plan lists the same 29 territory entries |
| Saily Caribbean Islands | €7.99 | €41.99 | 29 entries; a different country list |
For 1 GB / 7 days, Horizon is €3.91 (55.9%) less than Ubigi and €4.90 (61.3%) less than Saily. For 10 GB / 30 days, Horizon is €20.80 (49.5%) less than Saily. Percentages use the competitor's listed price as the denominator and are rounded to one decimal place. These savings apply to the quoted packages; the Saily comparison is useful only if your required stops are covered by both products. Equal destination counts do not prove equal coverage.
We checked advertised prices and coverage, not speed or reliability in the field. Prices can change. Open the linked provider pages and compare the final checkout total and country list before paying.
Which Greater Caribbean plan fits your trip?
The other checked Horizon options are 3 GB / 15 days for €8.79 and 10 GB / 7 days for €16.19. A seven-day and a thirty-day offer can have the same data allowance but a different useful travel window. Include arrival and departure days. For one island, compare its own country plan; a shared regional allowance is useful when your itinerary crosses several included destinations.
The previous Horizon Caribbean plan is retired from new sales. Its product URLs now lead to Greater Caribbean. The checked old prices were €4.99 for 1 GB / 7 days and €30.99 for 10 GB / 30 days. Greater Caribbean costs €1.90 and €9.80 less respectively. Existing purchases keep their original coverage and validity; a redirect does not upgrade or move an installed eSIM.
Using an eSIM on a Caribbean cruise
Greater Caribbean uses terrestrial mobile networks at covered land destinations. It does not include maritime or satellite connectivity and does not provide internet in open water. Ship Wi-Fi is a separate service. At sea, use airplane mode and turn Wi-Fi back on separately when using ship Wi-Fi; this also helps avoid unintended maritime roaming on your home line.
Check the jurisdiction of every port and private island, not just the cruise itinerary's marketing name. A beach cay is not a separate coverage country, and being near a covered island does not guarantee reception. Download meeting points, tickets and the return-to-ship time before leaving Wi-Fi.
Setup, hotspot and refunds
Use an unlocked eSIM-compatible device. Install over Wi-Fi, then follow the installation guide. Select Horizon for mobile data and enable data roaming on the Horizon line when you need it at a covered destination. Buying or installing does not start validity: the first connection to a supported network in a covered destination does. There is no deadline for first use.
Hotspot sharing is free on every Horizon plan. These fixed-data plans have no throttling; the allowance is finite. Horizon grants a full refund on request for used or unused plans, with no time limit. See the refund policy.
