ESIM.DOG 🐶 does not provide an unlimited‑data eSIM for Cuba. All plans listed for Cuba have a data cap of 50GB and a fixed validity period, ranging from 1 day to 90 days. For example, the “🛜 Cubacel Cuba - Essential Coverage (50GB/20Days) - Amber route” plan offers 50GB of data for 20 days at a price of $223.24 USD, while the “⚡️ Cubacel Cuba - Best Coverage (50GB/90Days) – Black route” plan provides the same data allowance for 90 days with tethering allowed and costs $528.98 USD.
Choosing one of these fixed data plans can be more cost‑effective for most travelers, unless an extremely heavy data user anticipates needing beyond 50GB, in which case a Pay‑as‑you‑go option would be necessary.
