nextSIM does not provide a truly unlimited data eSIM specifically for Slovakia. All plans that carry the word “Unlimited” offer only 1 GB per day (or 2 GB per day with a reduced speed of 2000 kbps after the allotted amount is consumed). After the 1 GB or 2 GB limit is reached the connection speed drops to the Reduced speed specified for each plan.
If a traveler needs a larger, constant data allowance, nextSIM offers fixed‑data packages. Examples include the eSIM GLOBAL 50GB 365Days Economy plan, which gives 50 GB of high‑speed data for a full year, and the eSIM EUROPE 50GB 30Days Premium plan, which supplies 50 GB for 30 days. These fixed‑data options are available for Slovakia and can be more cost‑effective for users who consume data heavily.
