ETravelSim does not provide a truly unlimited high‑speed eSIM for Slovakia. Plans that carry “Unlimited” in the name give 4 GB of high‑speed data per day and, once that daily limit is reached, the connection is throttled to a reduced speed of 128 kbps. If you need a larger uninterrupted data allowance, fixed‑data options are available; for example, a 50 GB plan valid for 30 days costs $49.99 USD and lets you use the full data amount at speed before any throttling. Another choice is the 4 GB/day plan for 30 days, priced at $65.00 USD, which provides the same daily limit but no additional data after the day ends. Selecting a fixed‑data plan generally offers better value unless you expect to consume a very large amount of high‑speed data.
