ChillaxSIM eSIM Data Plans for Czech Republic

ChillaxSIM does not have a truly unlimited data eSIM for the Czech Republic. All plans that carry “unlimited” in the name provide only 1GB of high‑speed data per day; after the daily quota is reached the speed is throttled to 5120kbps.
For travelers who need a larger, non‑capped amount of data, ChillaxSIM offers fixed‑data plans. A 100GB plan is available for 30 days at $47.90 USD, and a 50GB plan for the same validity is priced at $28.18 USD. Both of these plans provide high‑speed data until the allotted quota is used, after which the speed drops to 128kbps. These fixed‑data options are often more cost‑effective for those who anticipate heavy usage.

ChillaxSIM does not provide any eSIM plans for the Czech Republic that include a phone number or SMS capability. Their offering for this destination is limited to data‑only plans. Travelers who need voice or messaging functionality can rely on internet‑based services such as WhatsApp, Telegram, or iMessage, which operate over the data connection.

ChillaxSIM offers 36 single‑country data plans that cover the Czech Republic, along with 16 multi‑country plans that include the country in their coverage. The plans are divided into two main types: daily data cap plans, where the data allowance resets each day, and fixed data cap plans, which provide a total data limit for the entire validity period. Prices for the available plans range from $1.00 to $71.60, and data caps span from 1 GB up to 100 GB.
