JamboSim eSIM Data Plans for Czech Republic

JamboSim does not provide a truly unlimited data eSIM for the Czech Republic.
All plans that use the “Unlimited” name grant 3GB of high‑speed data each day; after the capped amount is used, the connection is throttled to 1000kbps.

If a traveler prefers a fixed data allowance, JamboSim offers several alternatives. For example, the 20GB/30 days plan is available for $6.99 and includes tethering, while a larger 100GB/180 days plan is available for $195.99. These fixed‑data plans can provide a more predictable cost for users who need more data than a daily 3GB allowance allows.

JamboSim provides a range of eSIM plans for travellers in the Czech Republic that include a phone number and the ability to send SMS messages. Each plan uses a US‑based dialing code (+1) and offers outbound voice and outbound SMS capabilities; incoming calls and SMS are not supported. The available plans vary in data allowance from 1GB to 20GB, validity periods from 7 days to 365 days, and prices from $11.99 to $105.99 USD. Travelers who need specific inbound or local Czech call and SMS features should confirm details directly with JamboSim before purchasing.

JamboSim provides 12 single‑country data plans that cover Czech Republic alone, and 47 multi‑country plans that include Czech Republic among their destinations. The available plans cover a price range from $1.99 to $185.99 and data caps from roughly 200 MB to 100 GB, with options that allow either a fixed data amount or a daily data cap, depending on the specific plan.
