Keep On Roaming eSIM Data Plans for Czech Republic

Keep On Roaming does not provide a genuine unlimited data eSIM for the Czech Republic. The plans that carry the word “Unlimited” in their name actually offer a capped amount of high‑speed data—generally 1GB per day—and after that limit the speed may be throttled, although the exact reduced speed is not specified.

Travelers who need more data can choose from fixed‑data plans that allow larger allowances. A common option is the KOR‑CZ‑20000MB‑30D plan, which supplies 20GB of high‑speed 5G data for 30 days at $19 USD. Other fixed plans in the dataset include 50GB for 30 days at $29 USD and 100GB for 30 days at $56 USD, offering higher capacity for those who consume more data.

Keep On Roaming does not offer Czech Republic eSIMs that include a phone number or SMS capability. The provider’s Czech Republic plans are data‑only, allowing high‑speed internet access but not inbound or outbound voice or text messages.

For travelers who still need to communicate, popular VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data connection to make calls and send messages without a local phone number.

Keep On Roaming gives travelers in the Czech Republic access to 15 single‑country plans and 26 multi‑country plans that cover the Czech Republic.
The single‑country options range from about $4 to $148 and offer 1 GB to 100 GB of data for 1 to 30 days of validity.
The multi‑country set covers the same price and data ranges, allowing a larger variety of destinations while still including Czech traffic.
Some plans feature a fixed data amount (25 plans) while others apply a daily data cap (16 plans). The fixed‑cap plans give a set amount of data for the full validity period, whereas the daily‑cap plans reset the allowance every day, which can be useful for short‑term trips or for people who normally use only a small amount of data each day. All of the available plans support tethering.
