nextSIM eSIM Data Plans for Cuba

nextSIM does not provide a truly unlimited data eSIM for Cuba; all plans listed have a specified data allowance. Although the plan names include “Unlimited, ” each plan contains a capped amount of high‑speed data and offers a reduced speed after the limit is reached—for example, the eSIM Cuba Unlimited 3Days Standard plan includes 1GB/day and drops to 512 kbps once the cap is exceeded.

Instead, nextSIM sells fixed‑data plans that can be more cost effective for most travelers. For instance, a 20GB plan valid for 30 days costs $248.66 USD, and a 10GB plan for the same duration costs $149.56 USD. These options provide a set amount of high‑speed data without the throttling associated with the “Unlimited” names.

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 provides 16 single‑country plans for Cuba, with no multi‑country options available. The catalogue includes eight daily data cap plans and eight fixed data cap plans. Prices span from roughly $23.38 up to $600.50, data caps range from 1 GB to 20 GB, and validity periods extend from 1 to 30 days. This gives travelers a broad selection of options, whether they prefer a fixed total amount of data or a cap that resets each day.
