mysim24 eSIM Data Plans for Czech Republic

mysim24 does not provide a plan with truly unlimited high‑speed data for travelers in the Czech Republic. The plans that carry the word “Unlimited” in their name give a high‑speed allowance of 1 GB per day or 2 GB per day. Once that allowance is reached the data speed is reduced to up to 512 kbps or 2000 kbps, respectively, and the daily allowance then resets after 24 hours.

If you need a larger, fixed amount of data you can choose from mysim24’s fixed data plans. For example, there are 20 GB and 100 GB plans that are valid for 31 days in the Czech Republic, and a 100 GB plan valid for 30 days. These provide a set data amount without the daily high‑speed limit that the “Unlimited” name suggests.

mySim24 does not offer eSIM plans that include a phone number or SMS capability for travel to the Czech Republic. Only data‑only eSIM plans are available from this provider.
Travelers who need voice or text messaging can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. However, because some destinations may restrict these services, users should confirm that the apps they rely on are accessible in the Czech Republic before purchasing a plan.

For the Czech Republic, mysim24 offers 33 single‑country plans and 137 multi‑country plans. Prices range from about $3.94 to $206.47, and available data caps go from 1 GB to 100 GB. Some plans are fixed‑data‑cap, giving you a set amount of data for the whole validity period, while others are daily‑data‑cap, providing a specific amount of data that refreshes each day.
