TailSim eSIM Data Plans for Czech Republic

TailSim does not offer a truly unlimited data eSIM for Czech Republic. The plans with “Unlimited” in the name give a daily high‑speed allowance of 3GB; once that limit is reached, the speed is reduced to 1000 kbps.

Travelers who need more data without a daily cap can choose one of TailSim’s fixed data plans, such as the 50 GB plan for 30 days or the 20 GB plan for 30 days, which provide a larger, fixed data allowance for the entire validity period.

TailSim does not provide an eSIM plan for the Czech Republic that includes a phone number or SMS capability. The provider offers only data‑only eSIMs for this destination. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in the Czech Republic before purchasing, as some destinations may block or restrict certain apps.

TailSim offers 14 single‑country data plans that cover the Czech Republic and an additional 14 multi‑country plans that include the Czech Republic among other destinations. Within the family of plans there are both fixed‑data‑cap options, which provide a set amount of data for the entire validity period, and daily‑cap options, which limit the amount of data available each day. Across its catalogue the price range spans from roughly $3.99 to $85.50 while data caps vary from 1 GB up to 50 GB, giving travelers a wide array of choices suitable for short‑term visitors or longer stays.
