RedSim eSIM Data Plans for Czech Republic

RedSim does not provide a true unlimited data eSIM for the Czech Republic. The plans that carry “Unlimited” in their name actually cap high‑speed data at 3GB per day for the Czechia‑only options and 5GB per day for the broader Europe options; after that limit is reached the speed drops to 1 Mbps for the rest of the day.

For travelers who need more data without the daily throttle, RedSim offers fixed‑data plans such as Czechia 20GB for 30 days (sold for $19.00 USD) and Europe (28 countries) 50GB for 30 days (sold for $47.60 USD). These plans give a single data allowance that must be used within the validity period, and they may be more cost‑effective for heavy‑data users than the daily‑restricted “Unlimited” options.

RedSim does not provide an eSIM for the Czech Republic that includes a phone number or SMS capability. The available plans are data‑only, so travelers will need to rely on internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage to communicate. While these VoIP services generally work over the data connection, some destinations may block or restrict certain apps, so it is advisable to confirm that the services you need are accessible in the Czech Republic before purchasing a plan.

For Czech Republic, RedSim offers 21 single‑country plans and 34 multi‑country plans, totaling 55 options. Prices range from $1.92 to $75.60, with data caps from 1 GB up to 50 GB. Among the plans, some provide a fixed data amount while others apply a daily data cap over the validity period.
