ZenSim eSIM Data Plans for Czech Republic

ZenSim does not provide true unlimited data eSIM plans for Czech Republic. Their plans labelled “Unlimited” actually have a cap of 3 GB per day; after reaching that limit, the data speed is not maintained at full speed. Users who need larger data allowances can choose from fixed‑data options such as the Czech Republic 20 GB – 10 days plan for $23.00 USD or the Czech Republic 10 GB – 10 days plan for $17.00 USD. These fixed plans may be more cost‑effective for travelers with substantial data needs and avoid the daily data cap inherent in the “Unlimited” named plans.

ZenSim does not provide eSIM plans for the Czech Republic that include a phone number or SMS. Only data‑only eSIM options are available. Travelers can still use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.

ZenSim provides eight single‑country data plans for the Czech Republic and an additional eight multi‑country plans that include the Czech Republic among other destinations. The available packages span a price range from roughly $11 to $57 USD and a data cap range from 3 GB to 20 GB over validity periods of 10 to 30 days. Within these options some plans impose a daily data cap, limiting the amount that can be used each day, while others offer a fixed total data allowance for the entire validity period. Tethering is permitted on several of the selections.
