4S eSIM eSIM Data Plans for Czech Republic

4S eSIM does not provide a truly unlimited data eSIM for the Czech Republic; every plan listed has a fixed data cap and a reduced speed of 1000 kbps after that limit is reached. The plans that include “Unlimited” in their names are only “unlimited” in the sense that the data allowance does not diminish over time, but the supply of high‑speed data is still capped.

Travelers who need more data can choose from the fixed‑data options. For example, a 5‑day plan with 50 GB of high‑speed data is available for roughly $20, and a 30‑day plan with 30 GB is available for about $30. These fixed plans are available to users who require large amounts of data without the throttling that occurs on the capped “Unlimited” plans.

4S eSIM does not provide any eSIM plan for the Czech Republic that includes a local phone number or SMS capability; only data‑only plans are offered. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain VoIP services, so it is advisable to confirm that the apps you rely on are accessible in the Czech Republic before purchasing a plan.

4S eSIM lists 54 single‑country data plans that cover the Czech Republic, as well as 108 multi‑country plans that include Czech among their destinations. The single‑country options offer caps ranging from 714 MB to 50 GB and prices between $1.42 and $195.83. Within these, 39 plans operate on a daily data cap while the remaining 123 provide a fixed data amount for the entire validity period, giving travelers the choice between a daily usage limit and a set amount of data for the life of the plan.
