eSimfly eSIM Data Plans for Czech Republic

eSimfly does not supply a truly unlimited data eSIM for the Czech Republic. Every plan marketed with an “Unlimited” title actually includes a fixed amount of high‑speed data each day, such as 1GB/day or 3GB/day; after the daily cap is reached the speed is reduced. Because a true unlimited plan is not available, travelers who expect no data limit will not find that option with eSimfly.

Users who need substantial data may choose one of eSimfly’s fixed‑data alternatives instead. For example, the 50GB 30‑day plan for Czech Republic offers a large volume of high‑speed data without the daily cap, while the 30‑day plan with 50GB gives similar coverage at a potentially lower cost. Selecting a fixed data plan can be more cost‑effective for heavy data users than opting for a plan that is labeled “Unlimited” but still imposes a daily limit.

eSimfly does not provide eSIM plans for the Czech Republic that include a phone number or the ability to send or receive SMS. Only data‑only eSIM options are available from this provider for Czech Republic travelers. If you need to place voice calls or send messages, you can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

eSimfly provides 21 single‑country data plans and 67 multi‑country plans that include the Czech Republic.
The single‑country offerings have prices ranging from about $1.56 for the smallest 1 GB option up to $140.23 for a 50 GB plan, while the multi‑country selections span a similar price spectrum from roughly $1.56 to $380.23.
Daily‑data‑cap plans are available in 29 different configurations, typically offering a set data allowance for each day of validity, whereas fixed‑data‑cap plans—59 in total—provide a pre‑determined amount of data valid for the plan’s entire duration.
