nextSIM eSIM Data Plans for Cuba

nextSIM does not provide a truly unlimited high‑speed eSIM plan for Cuba. The plans that carry “Unlimited” in their name actually offer a fixed data allowance—either 1GB or 2GB per day or per plan—after which the speed is throttled to 512kbps or 2000kbps. For travelers who expect to use more data, nextSIM offers fixed‑data plans such as the 20GB 30Days, 10GB 30Days, 5GB 30Days, and 3GB 30Days options, which provide a set amount of high‑speed data without any throttling. Choosing one of these fixed data plans can be more cost‑effective if a user anticipates heavy data usage rather than relying on a capped “Unlimited” plan.

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.
