nextSIM eSIM Data Plans for Cuba

NextSIM does not have a truly unlimited high‑speed data plan for Cuba. All plans titled “Unlimited” provide a fixed amount of data—1GB or 2GB—before the speed drops to a reduced rate of either 512kbps or 2000kbps. After this threshold the connection is throttled, so the plan is not considered unlimited in the full‑speed sense.

Travelers who need more data can choose from the high‑cap fixed plans offered by NextSIM. For example, the 20GB plan for 30 days costs $254.83 USD, and the 10GB plan for 30 days costs $153.28 USD. These plans offer consistent high‑speed access for the specified duration without the speed reduction that occurs on the “Unlimited” plans.

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.
