Concrete data for students
Data for a stay in Czechia with no contract, one eSIM for Erasmus across Europe, Flex for a whole semester, or a pack for a single country.

Why students
Built for a student budget
Instead of a 300–700 CZK plan
No need to pay a monthly plan all year. Buy data only when you actually need it — for exams, holidays and between semesters.
Ready for Erasmus
One eSIM covers an exchange across Europe. No hunting for a local SIM in a foreign country or language.
No commitment after exams
A one-off pack ends by itself once used up; Flex cancels in one click. No contract to deal with after school.

FAQ
Short answers for students
Does the eSIM work with no contract or commitment?
Yes. You buy a data pack or a monthly Flex, pay by card, and the QR code arrives by email after payment. With Flex you cancel renewal anytime in management; a one-off pack ends by itself once used up.
How fast do I get the QR code?
The QR code arrives by email after payment confirmation. You install it on your phone and turn data on whenever you need it.
Is it good for an Erasmus across several countries?
Yes. For an exchange across Europe a multi-country eSIM fits well — one install covers the whole trip and you avoid a new SIM at every border.
Will I lose my number?
No. The eSIM runs as a second, data-only line. Your main SIM with your number keeps receiving calls, SMS and verification codes from your bank and school.
What about the plan after the semester ends?
A one-off pack ends by itself once used up or expired. Flex you cancel anytime in management, so once you are back home you pay nothing more.
