Frequently Asked Questions About Caribbean eSIM

Does Caribbean eSIM work on all cruise ships?

Caribbean eSIM works when you're on land at port destinations, not while sailing between islands. The eSIM automatically connects when your ship docks at covered Caribbean islands including Dominican Republic, Jamaica, Barbados, Aruba, and 14 other destinations.

How much data do cruise passengers typically use?

Most cruise passengers use 2-5GB per day while in port for navigation, social media, photo uploads, and video calls. Holafly's unlimited Caribbean eSIM plans eliminate data anxiety, letting you share experiences without watching usage meters.

Can I use Caribbean eSIM for hotspot sharing?

Yes, Holafly Caribbean eSIM includes 500MB daily hotspot allowance. This covers basic sharing with family members for messaging apps and light browsing, though heavy video streaming may exceed the daily limit.

Which Caribbean cruise ports have the best eSIM coverage?

Major ports like Barbados (Bridgetown), Dominican Republic (Punta Cana), Jamaica (Ocho Rios), and Aruba (Oranjestad) offer excellent 4G coverage. Smaller islands may have 3G speeds, but connectivity remains reliable for typical cruise passenger needs.

Do I need different eSIMs for each Caribbean island?

No, one Holafly Caribbean eSIM covers 18 islands including all major Royal Caribbean, Norwegian, and Celebrity cruise ports. The eSIM automatically connects at each destination without requiring manual switching or additional purchases.

How does Caribbean eSIM compare to cruise ship WiFi?

Caribbean eSIM costs $5.99-6.73 per day for unlimited shore-based data, while cruise ship WiFi costs $15-30 daily and only works onboard. eSIM provides faster speeds and works perfectly for shore excursions, navigation, and social media posting.

Can I buy Caribbean eSIM after starting my cruise?

Yes, you can purchase and install Caribbean eSIM during your cruise using ship WiFi. However, buying before departure ensures customer service availability and lets you test the setup before reaching your first port.

Does Caribbean eSIM work in Mexico and Central America?

The Caribbean-specific eSIM covers Caribbean islands only. For Western Caribbean cruises visiting Cozumel (Mexico) or Costa Rica, you'll need separate Mexico or Central America eSIM plans from Holafly.

What happens if I exceed the daily hotspot limit?

After using 500MB of hotspot data daily, personal device usage continues unlimited, but hotspot sharing may be throttled. Most families find 500MB adequate for sharing maps, messaging, and basic browsing among 2-3 devices.

Can I get a refund if Caribbean eSIM doesn't work?

Holafly offers up to 6 months for refund requests on unused eSIMs. If you experience technical issues, their 24/7 support team can troubleshoot connectivity problems or provide refunds for legitimate technical failures.
