Airalo eSIM Data Plans for Czech Republic

Airalo does not provide a truly unlimited high‑speed data plan for Czech Republic. The plans that carry the word “Unlimited” in their name actually cap usage at 3GB per day; after that limit is reached, speed is reduced to 1000kbps.

Travelers can instead choose from fixed‑data options that give larger, unthrottled allowances. For example, a 100GB plan is available for 180 days at $185.00 USD, and a 50GB plan is available for 30 days at $36.00 USD. These fixed‑data plans may be more cost‑effective for heavy data users than the capped “Unlimited” options.

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 lists 19 single‑country data plans and 52 multi‑country plans that include the Czech Republic, covering a price range from $4 to $185. The data caps offered span from 1 GB to 100 GB, and validity periods range from 3 to 365 days. Plans are divided into fixed data caps—59 of them in total—and daily data cap options—12 in total—allowing customers to choose between a set amount of data or a daily limit.
