Nomad does not provide a truly unlimited data eSIM for the Czech Republic. The plans listed as “unlimited” give a maximum of 2GB per day; once that allowance is reached the speed is throttled to 1000 kbps, so high‑speed data is still limited.
Instead, Nomad offers fixed data plans that allow larger, non‑capped data allowances. For example, a 30‑day plan gives 50GB of high‑speed data, and another 30‑day plan offers 20GB. If shorter periods are preferred, there are 3‑, 5‑, 7‑ or 10‑day plans each providing 2GB of high‑speed data per day before the speed reduction applies.
