ZenSim does not provide a truly unlimited data eSIM for Slovakia. The plans that carry “Unlimited” in their names offer a fixed high‑speed allowance of 2 GB per day, after which the connection speed is reduced. For travelers looking for no‑cap high‑speed data, the only options are the fixed‑data packages. Examples of these are the Slovakia 20 GB - 30 days plan, which delivers 20 GB of high‑speed data valid for 30 days at a price of $24.00 USD, and the Slovakia 10 GB - 10 days plan, which provides 10 GB for 10 days at $15.00 USD. Choosing a fixed data plan can be more cost effective unless a user expects to consume data beyond the 2 GB daily allowance of the “Unlimited” labels.
