nextSIM eSIM Data Plans for Cuba

nextSIM’s plans for Cuba that carry the word “Unlimited” are actually capped. Each of those options provides a fixed amount of high‑speed data—either 1GB or 2GB per day—with a reduced speed applied once the limit is reached (512kbps for the 1GB plans and 2000kbps for the 2GB plans). There are no truly unlimited high‑speed data plans available through nextSIM for Cuba.

If a traveler needs more data without the speed cut‑off, nextSIM offers fixed‑data plans such as 20 GB for 30 days, 10 GB for 30 days, 5 GB for 30 days, or 3 GB for 30 days. These fixed plans provide all‑high‑speed data throughout the validity period and can be a more cost‑effective choice for most users compared with the capped “Unlimited” options.

nextSIM does not offer any eSIM plans for Cuba that include a phone number or SMS capability. The provider only supplies data‑only eSIMs, so travelers cannot receive or make standard voice calls or text messages through the local network. However, data connectivity can be used with popular VoIP applications such as WhatsApp, Telegram, or iMessage for communication. Travelers should verify that the VoIP services they rely on are accessible in Cuba before purchasing a plan.

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.
