ZenSim eSIM Data Plans for Czech Republic

ZenSim does not provide a truly unlimited high‑speed data eSIM for Czech Republic. The plans that carry the name “Unlimited” actually offer a 3GB/day high‑speed allowance and after that limit is reached the speed is reduced, though no specific reduced speed is listed. Therefore these are not unlimited in the sense of having unrestricted high‑speed data.

Travelers who need more data can choose a fixed‑data plan, such as the 40GB plan valid for 30 days at 45 USD, or the 20GB plan available for 10 or 30 days. These options give a larger amount of high‑speed data without the daily cap found in the “Unlimited” 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.
