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 nine single‑country data plans for the Czech Republic and another nine multi‑country plans that include Czech coverage. The plans are priced from about $11 to $57 and offer data caps ranging from 3 GB to 40 GB. Among these, four plans feature daily data caps, limiting the amount of data usable each day, while fourteen plans have fixed data caps that provide a set amount of data for the full validity period. Plan validity ranges from 10 to 30 days, and many of the plans allow tethering.
