EZsim does not provide an unlimited data eSIM for the Czech Republic. All available plans list a specific data cap and a fixed validity period. For example, EZsim offers a 20GB plan valid for 30 days, a 10GB plan also valid for 30 days, as well as smaller bundles such as 5GB, 3GB, and 1GB for 30 days or 7 days.
Travelers who need large data allowances can choose one of these fixed‑data plans. The 20GB/30Days plan, priced at $11.55 USD, and the 10GB/30Days plan, priced at $6.00 USD, are among the most generous options. Since the data is bundled and must be used within the validity window, these plans can be more cost‑effective for passengers who consume a moderate amount of data during their stay.
