nextSIM eSIM Data Plans for Cuba

nextSIM does not provide a truly unlimited high‑speed data eSIM for Cuba. All plans marketed with “Unlimited” in the name actually include a capped amount of high‑speed data that sticks to the specified quantity before the speed is throttled. For example, the eSIM Cuba Unlimited 1Days Standard plan offers 1GB of high‑speed data for 1 day, after which the speed drops to 512kbps. The eSIM Cuba Unlimited Plus 1Days Standard plan provides 2GB before the speed reduces to 2000kbps. Similar capped‑capability plans exist for 3, 5, 7, and 10 days with the same pattern of reduced speed after the limit.

If a user requires a larger data allowance, nextSIM offers fixed‑data plans as alternatives, such as 20GB for 30 days, 10GB for 30 days, 5GB for 30 days, and 3GB for 30 days. These plans deliver a set amount of high‑speed data throughout the validity period and may be more cost‑effective for travelers who anticipate substantial data usage.

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.
