The best option is to use sim card with cash collection payment (Inkaso). For free it is possible to do with "O2 Fer na fakturu" in O2 or "Sikovna Prima na fakturu" in Orange. Card validity is infinity, because you will pay 0€ each month :D. In both cases you can do it in stores or online through this links:

But if you really want prepaid sim card i recommend 4ka, it cost 4€ with 4€ credit and validity is 16 months.
