Price per GB in Czechia: what our data shows
According to the Datadopt Observatory, the lowest price per GB recorded in Czechia comes down to 0.08 €/GB, across a sample of 2,555 fixed-volume offers retained for the measurement. That floor is reached on large data bundles : a 5 GB plan over 30 days costs noticeably more per GB. The real differentiator is still the depth of the offer : the more plans compete, the easier it is to find the duration and data volume that fit your trip.
