MobileSIM eSIM Data Plans for Czech Republic

MobileSIM does not provide a truly unlimited data eSIM for Czech Republic. The plans that use “Unlimited” in the name actually offer 3GB of high‑speed data per day and then reduce speed to 1000 kbps after the daily allowance is reached. For travelers who need a large amount of data without the daily cap, MobileSIM sells fixed data plans such as the 20 GB for 30 days plan or the 10 GB for 30 days plan, which provide a higher total data allowance at a fixed cost and are valid for 30 days.

MobileSIM does not provide eSIM plans for the Czech Republic that include a phone number or SMS capability. Their only Czech Republic offers are data‑only plans.

Travelers who need voice and messaging can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain apps or VoIP services, so it is advisable to verify that the required apps will work in the Czech Republic before purchasing.

MobileSIM offers 12 single‑country plans that cover the Czech Republic exclusively and 10 multi‑country plans that include the Czech Republic among other destinations. The plans range from a data cap of 200 MB to 60 GB, with prices from roughly $2.30 to $165 depending on validity and data limits, and include both fixed data amount options and daily data cap variants.
