Lumbus does not have a plan that gives travelers unlimited high‑speed data for the Czech Republic. All Czech Republic “Unlimited” plans listed by Lumbus provide 3GB of 5G data per day, after which the connection is throttled to 1000kbps. Therefore, the plans are fixed‑data packages, not true unlimited offers. For example, the Czech Republic Unlimited 3GB/day for 30 days costs $63.99 USD, and the Europe 35 Unlimited 3GB/day for 30 days costs $69.99 USD, both featuring the same daily data allowance and reduced speed after the limit is reached. While these options give a large amount of data, they are not unlimited, and travelers who need more use may consider topping up or selecting larger fixed‑data bundles such as the 50GB 30‑day or 100GB 180‑day plans.
