eSimfly eSIM Data Plans for Czech Republic

eSimfly does not provide a plan with truly unlimited high‑speed data for Czech Republic. All plans marked “Unlimited” actually include a fixed data allowance—most commonly 1 GB per day or 3 GB per day for a given validity period—and the speed may be throttled once that limit is reached. The name “Unlimited” is therefore misleading; the plans do not offer high‑speed data without a cap.

For travelers who need a larger data budget, eSimfly offers fixed‑cap plans such as the 100 GB plan valid for 30 days and several 50 GB plans also valid for 30 days. These plans give a fixed amount of high‑speed data and may be more cost‑effective for heavy data users.

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 offers 24 single‑country data plans and 67 multi‑country data plans for Czech Republic. The available plans span a price range from about $1.56 to $380.23 and a data cap range from 1 GB up to 100 GB. Some plans provide a fixed data amount for the entire validity period, while others apply a daily data cap that allows a set amount of data each day. The validity of plans can last from one day to a full year.
