nextSIM eSIM Data Plans for Cuba

nextSIM does not provide a truly unlimited data eSIM for Cuba. The plans that include “Unlimited” in their names actually come with a capped data allowance; after the set amount is used, the speed drops to a reduced rate – 512kbps for the standard tiers and 2000kbps for the Plus tiers.

Travelers who need a larger data budget can choose from fixed‑data plans instead. For example, nextSIM offers a 20GB 30‑day plan priced at $249.95 USD and a 10GB 30‑day plan at $150.34 USD. These options provide a fixed amount of high‑speed data without the speed throttles that accompany the “Unlimited” names and can be more cost‑effective unless a user is an extremely heavy data consumer.

nextSIM does not provide a phone number or SMS capability for its Cuba eSIM plans. Only data‑only eSIMs are offered for that destination.

You can still communicate from your device using popular VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over the data connection without requiring a local phone number or SMS capability.

nextSIM offers 17 single‑country plans for Cuba, with no multi‑country options available. The single‑country plans are split into two categories: eight daily data cap plans that reset each day and nine fixed data cap plans that provide a set amount of data for the full validity period. Prices across these plans range from about $23.36 to $599.90, while data caps span from roughly 1 GB up to 20 GB and validity can be as short as one day or as long as thirty days. This range accommodates different usage needs and trip lengths.
