eSimfly eSIM Data Plans for Caribbean

eSimfly does not provide a true unlimited data eSIM for the Caribbean. The only plans that use the word “Unlimited” in their name, such as Caribbean Islands Unlimited 7 Days, actually cap data at 3 GB per day; after that limit the speed is reduced, though the throttled rate is not specified in the data. Travelers who need larger data allowances can choose fixed‑data plans from eSimfly, for example the Discover Global 20 GB 365 Days plan or the Caribbean Islands 10 GB 30 Days plan, both of which offer a set amount of high‑speed data for a specified validity period. Selecting a fixed data plan can be more cost effective for most users, unless a traveler is an extremely heavy data consumer who would prefer unlimited high‑speed data.

eSimfly does not offer Caribbean eSIM plans that include a phone number or SMS capability. The provider’s Caribbean offerings are data‑only, so there is no way to make or receive standard voice calls or text messages via the device’s native telecom network.

Travelers who need voice or messaging can still use internet‑based services such as WhatsApp, Telegram, and iMessage, which work over the data connection supplied by the eSIM.
