Roamingo does not provide a truly unlimited data eSIM plan for Czech Republic. The only plan with a name that includes “Unlimited” is the Europe Unlimited for 1 day plan, which actually limits high‑speed data to 2GB; after that amount the speed is reduced, though the exact throttled speed is not specified in the data.
Instead, Roamingo offers fixed‑data plans for Czech Republic that range from 3GB up to 20GB with a validity of 30 days. For example, the Czechia 20GB for 30 days plan costs $25.50 USD, while the Czechia 10GB for 30 days plan is $14.50 USD. Choosing one of these fixed‑data plans may be more economical unless a traveler requires extensive high‑speed data beyond the 2GB limit.
