eSimfly eSIM Data Plans for Cuba

eSimfly does not offer a truly unlimited data eSIM plan for travelers in Cuba. All of the plans listed under the “Unlimited” name actually provide 1 GB of high‑speed data per day, so the amount of data that can be used is capped. After the daily 1 GB allowance is reached, the data speed is generally reduced, although the exact throttled speed is not specified in the plan details.

Instead, eSimfly sells fixed‑data eSIM plans for Cuba that include larger data allowances. For example, travelers can purchase a 20 GB plan valid for 30 days, or a 10 GB plan also valid for 30 days. These fixed data plans may be more cost effective for users who need more than 1 GB per day but do not require a truly unlimited data option.

eSimfly does not provide a Cuba eSIM that includes a phone number or SMS functionality. The provider’s offerings for Cuba are limited to data‑only plans, which give internet access without voice or text messaging capabilities. Travelers who need to communicate while in Cuba can rely on VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection to make calls and send messages without requiring a local phone number.

eSimfly offers 11 single‑country data plans for Cuba. No multi‑country options are available. The plans are priced between $29.90 and $319.96, with data caps ranging from 1 GB to 20 GB over validity periods of 1 to 30 days. Four of these plans have a daily data cap, limiting usage each day, while the remaining seven are fixed‑data plans that provide a set amount of data for the entire validity period. Tethering is allowed on some plans.
