MobileSIM eSIM Data Plans for Czech Republic

MobileSIM does not provide a truly unlimited data eSIM for the Czech Republic. Plans that carry “Unlimited” in their name, such as the Czechia Unlimited data for 3‑30 days, actually allow 3GB per day. After the 3GB limit is reached, the speed is reduced to 1000kbps. For travelers who need consistent high‑speed data, MobileSIM offers fixed‑data plans instead. Examples include the Czechia 20GB plan valid for 30 days and the Czechia 10GB plan also valid for 30 days. These fixed‑data plans may be more cost‑effective for users who consume large amounts of data.

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.
