Description
Island-hopping in the Caribbean is the classic shape of a trip here — cruise itineraries that hit four ports in a week, sailing charters through the Grenadines, or a structured St Lucia-Martinique-Dominica chain using the ferry between them. The Blikst Caribbean eSIM covers 25 island nations and territories on one profile, which means you don't swap SIMs at every port. Coverage includes the Bahamas, Turks and Caicos, Jamaica, the Cayman Islands, the ABC islands (Aruba is not in the list, but Bonaire, Sint Eustatius and Saba, and Curaçao are), Bermuda, the Lesser Antilles from Anguilla down through St Kitts, Antigua, Dominica, Martinique, St Lucia, St Vincent and the Grenadines, Grenada, Barbados, Trinidad and Tobago, and the three Guianas region (French Guiana, Guyana, Suriname). El Salvador is also included.
How the network roams across islands
The eSIM attaches to different carrier partners on different islands — Digicel is the single most common, with reach across most English-speaking Caribbean states; Cable and Wireless (Flow) covers many of the same islands plus Turks and Caicos; Aliv operates in the Bahamas; Telefónica is the partner in El Salvador; Outremer Télécom handles French Antilles; Curaçao's local carriers cover the ABC-adjacent islands. The plan switches carriers automatically as you move between islands — you'll notice the network name change on your phone, which is normal. Speeds run 3G / 4G / 5G depending on the island and carrier.
Coverage by island region
The Bahamas (Nassau, Paradise Island, Freeport, the Exumas) has good Aliv 4G on the main populated cays and drops on uninhabited ones. Jamaica's Digicel covers Kingston, Montego Bay, Negril, and Ocho Rios with strong 4G. Turks and Caicos runs on Cable (Flow) with solid Provo coverage. The Cayman Islands (Grand Cayman, Little Cayman, Cayman Brac) have full 4G on Grand, lighter on the sister islands. Barbados, Antigua, St Lucia, Grenada, St Kitts, and St Vincent all have Digicel 4G through main settlements and the resort coasts. Martinique and French Guiana use Outremer and are technically French territory with better-than-average regional coverage. Dominica has patchy coverage in the interior rainforest; the coast is fine. Sailing through the Grenadines between Bequia, Mustique, Canouan, and Union Island is mostly in-signal near the populated islands and offline on transits.
Border and port behaviour
Cruise passengers benefit most here. Instead of paying $15 per day in at-sea roaming (where available) or juggling multiple port-specific SIMs, the plan attaches to whichever local tower is in range when the ship is in port. It doesn't work mid-Atlantic or between islands when you're not near any tower. Charter sailors in the BVI, St Vincent and the Grenadines, or St Lucia's Pitons area will see coverage pop back on as they near each anchorage and drop during open-water transits. Flights between islands (LIAT, Caribbean Airlines, Interisland) are short enough that the eSIM simply hands off on landing.
What's NOT in the plan
A few notable Caribbean destinations aren't on this profile: Aruba, the Dominican Republic, Puerto Rico, Cuba, and the US Virgin Islands. For those, use country-specific plans or, in Puerto Rico's case, the North America regional plan. Also note El Salvador appears on this Caribbean plan as a network-routing artefact — if your trip is El Salvador-focused, a country-specific plan is more cost-effective.
Cost vs. cruise roaming or island SIMs
Cruise-line roaming add-ons typically run $15–$20 per day. Buying a SIM at each port is a non-starter for anyone with more than two stops — you'd spend the cruise queuing at Digicel shops. A Caribbean eSIM lets you step off the gangway in Basseterre, St John's, Castries, or Bridgetown already online. For land-based island-hopping using LIAT or inter-island ferries, the cost advantage over four separate SIMs is significant.
Local apps across the region
- WhatsApp: The connective tissue of Caribbean tourism. Villa hosts, charter captains, tour operators, island taxi drivers — all WhatsApp-first.
- Google Maps: Reliable on main roads in most islands. Dominica's interior, Grenada's nutmeg-growing inland, and St Vincent's leeward side need offline tiles.
- Navionics or Windy: If you're sailing, both are standard.
- Ride apps: Vary by island. Uber doesn't cover most of the region; local dispatch numbers and WhatsApp are the norm in smaller islands. Jamaica has some app-based options.
Plan sizing by trip length
A one-week cruise with 4–5 port days works on 3–5 GB. A two-week multi-island land trip wants 10 GB. A month-long sailing charter through the Grenadines or down-island fits 20 GB.
Install on home Wi-Fi before you fly, land or dock at the first island, and the plan attaches to Digicel, Flow, Aliv, or Outremer depending on where you are.

I used to have 3 mobile but the internet connection was not the best, that’s why I started to use Blikst and I find it very useful
eSIM FAQ
It covers 25 island nations and territories on one profile, so you don't swap SIMs at every port. That includes the Bahamas, Turks and Caicos, Jamaica, the Cayman Islands, Bonaire, Sint Eustatius and Saba, Curacao, Bermuda, Anguilla, St Kitts and Nevis, Antigua and Barbuda, Dominica, Martinique, St Lucia, St Vincent and the Grenadines, Grenada, Barbados, Trinidad and Tobago, French Guiana, Guyana, Suriname, and El Salvador. Note Aruba, the Dominican Republic, Puerto Rico, Cuba and the US Virgin Islands are not included.
The eSIM attaches to different carrier partners on different islands. Digicel is the most common, reaching most English-speaking Caribbean states; Cable and Wireless (Flow) covers many of the same islands plus Turks and Caicos; Aliv operates in the Bahamas; Telefonica is the partner in El Salvador; Outremer Telecom handles the French Antilles; and Curacao's local carriers cover the ABC-adjacent islands. Speeds run at 3G, 4G or 5G depending on the island and carrier.
Yes. One profile covers all 25 islands and territories, and the plan switches carriers automatically as you move between them. You'll notice the network name change on your phone, which is completely normal. It does not work mid-Atlantic or on open-water transits when you're not near any tower, so cruise and charter signal comes and goes as you near each port or anchorage and drops on the crossings in between.
After purchase you'll get a confirmation email with your eSIM details within minutes. Install it on home Wi-Fi before you fly by scanning the QR code provided, which adds the eSIM as a new line on your phone. Activation is automatic: the eSIM activates upon your arrival in the Caribbean, attaching to Digicel, Flow, Aliv or Outremer depending on where you land or dock, giving you immediate connectivity at your first island.
Most modern smartphones are fully compatible, though a few exceptions exist, so check our detailed compatibility list to confirm your device. Your phone also needs to be carrier-unlocked. On an iPhone you can check eSIM support under Settings, General, About and look for an EID number; on Android it's in the network or SIM settings. If those appear, you're almost certainly good to go.
It depends on your trip shape. A one-week cruise with four or five port days works comfortably on 3 to 5 GB. A two-week multi-island land trip, hopping by LIAT or inter-island ferry, suits about 10 GB. A month-long sailing charter through the Grenadines or down-island fits roughly 20 GB. Navigation and WhatsApp are the main daily drains, so lean toward the larger size if you'll be mapping new islands often.
Yes, tethering and hotspot use are supported, so you can share your connection with a laptop, tablet or a travel companion's phone. That's handy on a charter or in a villa where one person's eSIM keeps the group online. Bear in mind your speed depends on the island and carrier, running anywhere from 3G to 5G, and signal drops on open-water transits when you're not near a tower.
This is a data plan, so it doesn't include a local Caribbean phone number for traditional calls or texts. Instead you call and message over the internet using apps like WhatsApp, which is the connective tissue of Caribbean tourism for villa hosts, charter captains and taxi drivers, alongside FaceTime. Because the eSIM is a separate digital line, you can leave your physical home SIM in the phone and keep your own number reachable.
