eSIM Caribbean

eSIM Caribbean: one prepaid data plan for 19 island destinations, from Jamaica to Barbados

Island trips rarely stay on one island. A Caribbean holiday might land in Jamaica, hop to the Cayman Islands and finish in Barbados, or work down the Leeward chain from Antigua to Saint Lucia by ferry and small plane. Buying a SIM at every jetty is impractical, and home roaming passes treat each island as a separate zone. An eSIM Caribbean plan is installed once, over Wi-Fi, before you fly, and connects automatically on every covered island. Your own number keeps working on your primary SIM throughout.

Islands, networks and switching between them

GlobaleSIM’s Caribbean plan covers 19 destinations, including Jamaica, Barbados, the Dominican Republic, the Cayman Islands, Bermuda, Antigua and Barbuda, Saint Lucia, Grenada, Dominica, Guadeloupe, Anguilla, Montserrat, Saint Kitts and Nevis, Saint Vincent and the Grenadines and the British Virgin Islands. The same plan also reaches a few islands well beyond the Caribbean: Mauritius, the Seychelles, Papua New Guinea and Saint Helena, Ascension and Tristan da Cunha. On each island the eSIM attaches to our partner network there, and moving between covered islands is automatic: the phone joins the new partner network on landing with no settings to change. Coverage is strong in capitals, resort areas and around airports; in mountainous interiors, on remote beaches and at sea it fades, as on every network.

Plans, prices and validity

The Caribbean prepaid data plan starts from $18 for 1GB, with 2GB, 3GB and 5GB also available. Validity follows the size: 1GB for 7 days, 2GB for 10 days, 3GB for 14 days and 5GB for 21 days. A week at a resort with maps, messaging and a daily batch of beach photos is comfortable on 1GB or 2GB. A two-week sailing or island-hopping route with booking apps, ferry timetables and video calls home should start at 3GB or 5GB and top up the Caribbean eSIM if needed. The validity clock starts only when the device first connects to a supported network on a covered island, so installing at home in advance costs nothing.

Installing your eSIM for the Caribbean

• Order online and the QR code arrives by email in minutes; there is nothing to collect at the airport.
• Install over Wi-Fi before departure on iPhone, Samsung Galaxy or Google Pixel. Data works only on the covered islands, not at sea.
• On arrival, set the eSIM as your data line and enable data roaming for it. Your primary SIM keeps your own number.
• Hotspot and tethering are supported, so a tablet or a travel companion can share the connection.
• Top up from the GlobaleSIM dashboard or app whenever you run low, with 24/7 human support on WhatsApp.

Calls and a phone number

The plan is data-only by default, and WhatsApp calls work well on data for reaching boat captains, taxi drivers and villa hosts. Add a voice-minutes bundle (+100, +200 or +300 minutes) at checkout and the Caribbean eSIM comes with a dedicated international phone number, US +1 or UK +44, for calls and SMS. That is useful for airlines, ferry operators and dive shops, and for receiving verification codes.

Tips for mobile data across the islands

Ferry and inter-island flight schedules change with the weather, so keep booking apps and airline messaging online. Taxi rates on many islands are fixed by zone rather than metered, and a quick map check helps. Resort Wi-Fi is often free but slow when everyone uploads sunset photos at once, and beach bars rarely have any. Cruise passengers should remember that data works only on the covered islands, not on board. If your holiday stays on one island, a single-island plan may be better value; the Caribbean plan is for routes that touch several.
