Why students
Built for a student budget
Instead of a 300–700 CZK plan
No need to pay for a recurring 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 once used up or expired. There is no long lock-in to deal with after school.

FAQ
Short answers for students
How does a one-off eSIM work?
Choose a data pack, pay by card and get the QR code by email after payment confirmation. The pack ends when it is used up or reaches its stated validity.
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?
Your primary SIM can keep receiving calls, SMS and verification codes. Whether the eSIM includes calls, SMS or a number is stated on the specific plan.
What about the plan after the semester ends?
A one-off pack ends when it is used up or expires. There is no automatic renewal to switch off after the semester.
