4S eSIM eSIM Data Plans for Caribbean

4S eSIM does not provide a truly unlimited high‑speed data eSIM for the Caribbean. The plans that include “Unlimited” in their name are fixed‑data plans; after the specified data amount is used, the speed is throttled to 1000 kbps. For example, the Global 10GB Unlimited‑5 Days plan delivers 2 GB of high‑speed data per day over five days, and the Global 5GB Unlimited‑7 Days plan gives 714 MB per day for seven days, each with a 1000 kbps reduced speed after the limit is reached.

If an unthrottled data allowance is preferred, 4S eSIM offers several fixed‑data options for Caribbean destinations. One such plan is the Global 50GB‑15 Days with a 50 GB allowance valid for 15 days at a price of $74.56 USD, and another is the Global 30GB‑30 Days plan that provides 1 GB per day over a month for $103.32 USD. These fixed plans can be more cost‑effective for travelers who need reliable high‑speed data and are not heavily data‑constrained.

4S eSIM does not provide an eSIM plan for the Caribbean that includes a local phone number or SMS capability. The available Caribbean eSIMs from this provider are data‑only, offering internet access but no call or text feature.

Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or limit access to specific apps or VoIP services, so it is advisable to confirm that the preferred applications will work in the intended Caribbean country before purchasing a plan.

4S eSIM offers two Caribbean‑focused plans. The Global plan includes Caribbean coverage of Antigua and Barbuda, Barbados, Bahamas, Curaçao, Dominica, Dominican Republic, Jamaica, Saint Kitts and Nevis, Cayman Islands, Saint Lucia, Puerto Rico, Turks and Caicos Islands, Saint Vincent and the Grenadines, and British Virgin Islands. The Caribbean+ plan covers Antigua and Barbuda, Anguilla, Barbados, Bahamas, Curaçao, Dominica, Dominican Republic, Grenada, Jamaica, Saint Kitts and Nevis, Cayman Islands, Saint Lucia, Montserrat, Puerto Rico, Turks and Caicos Islands, Saint Vincent and the Grenadines, and British Virgin Islands.
