Airalo eSIM Data Plans for Czech Republic

Airalo does not provide a truly unlimited high‑speed eSIM plan for travel in the Czech Republic. The plans marketed as “Unlimited” in the Airalo catalogue give subscribers 3GB of data per day and, after the limit is reached, the connection speed is reduced to 1000kbps. This throttling means the data are no longer unlimited in the sense of unrestricted high‑speed use.

Travelers who need more data can purchase fixed‑data plans instead. For example, Airalo offers a 50GB plan for 30 days at $36.00 USD and a 100GB plan valid for 180 days at $185.00 USD. These fixed‑data options provide larger capacities without the post‑limit speed reduction, and they may be more cost‑effective for heavy data users.

Airalo offers a Czech Republic eSIM that includes a local phone number and SMS functionality. The plan, named O2 – 10 GB, provides 10 GB of high‑speed data for 30 days at a price of $16.00 USD. The phone number carries the Czech dialing code +420, and users can make and receive voice calls, as well as send and receive SMS. For specific requirements or updates, it is advisable to confirm the details directly on Airalo’s site.

Airalo’s catalogue for the Czech Republic includes 19 single‑country data plans and 58 multi‑country plans. The available packages span a price range from about $4 to $185 and a data budget that can be as low as 1 GB or as high as 100 GB. Some offers are fixed data caps (a set amount of data that lasts the validity period), while others operate with a daily data cap that limits the amount you can use each day. In both cases the validity can extend from a few days up to a full year.
