nextSIM eSIM Data Plans for Cuba

NextSIM does not provide a true unlimited data eSIM for Cuba. The plans that carry the “Unlimited” name actually cap high‑speed data to 1 GB or 2 GB per day and then throttle the speed to 512 kbps or 2000 kbps. For travelers who need more capacity without such throttling, nextSIM offers fixed‑data plans such as 20 GB, 10 GB, 5 GB, or 3 GB valid for 30 days.

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.
