nextSIM eSIM Data Plans for Cuba

There is no nextSIM plan that provides unlimited high‑speed data in Cuba. All plans listed under the “Unlimited” name contain a fixed data allowance—ranging from 1 GB to 2 GB per day—after which the speed is reduced to 512 kbps or 2000 kbps.

Travelers who need larger data amounts can choose a fixed data plan. For example, nextSIM offers the eSIM Cuba 20GB 30Days Standard, which delivers 20 GB of full‑speed data over 30 days, and the eSIM GLOBAL 50GB 30Days Premium, providing 50 GB of high‑speed data across Cuba and 169 other countries. These fixed plans may be more cost‑effective for users who intend to consume significant data during their stay.

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 offers 20 single‑country plans and 26 multi‑country plans that cover Cuba; these plans range in price from about $20.65 to $1, 261.66 and provide data caps from 1 GB up to 50 GB (availability varies by validity period). The single‑country options focus on a fixed data amount for a set duration, while the multi‑country packages usually bundle data for several destinations, allowing a lower per‑GB cost or broader coverage across the Caribbean.
