nextSIM eSIM Data Plans for Cuba

nextSIM does not provide a plan with truly unlimited high‑speed data for Cuba. The plans that carry the wording “Unlimited” actually include 1 GB or 2 GB of high‑speed data; after that amount the speed is reduced to 512 kbps or 2000 kbps as listed. Travelers who need more data can choose from a range of fixed‑cap plans, such as the 20 GB 30 days, 10 GB 30 days, 5 GB 30 days, 3 GB 30 days or the 2 GB 15 days plan. These options allow a larger amount of data at full speed before any throttling occurs and may be more cost‑effective for heavy data users.

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 data plans for Cuba. There are no multi‑country plans available. The plans vary in price from about $23.38 to $600.62 and in data allowance from 1 GB to 20 GB, with validity periods ranging from 1 to 30 days. Half of the plans feature a daily data cap, which resets each day, while the other half have a fixed data cap that is available for the entire validity period.
