ETravelSim does not provide a high‑speed data plan with no limit for the Czech Republic. All plans that use the word “Unlimited” actually give 4GB of high‑speed data each day, and once that daily quota is reached the speed drops to 128kbps; the data cap is enforced after the limit, so the plan is not truly unlimited.
ETravelSim offers fixed‑data alternatives that may be more suitable for heavy data use. For instance, the Travel eSIM for Europe 50 GB – 30 Days / Data Only plan provides 50 GB of high‑speed data for 30 days, and a similar 50 GB plan is available that covers only the Czech Republic. These high‑volume plans can be more cost‑effective for travelers who expect to use large amounts of data.
