Czech eSIM at $0.95/GB is fair — local prepaid not significantly cheaper, making eSIM the better value proposition. Airalo offers Czech Republic plans through both O2 Czech Republic and T-Mobile CZ, making it the stronger choice when network redundancy matters — particularly in rural areas where O2 Czech Republic coverage thins. Holafly covers Czech Republic with unlimited daily plans from $2.62/day. It is the correct pick for travelers streaming video, taking video calls, or tethering a laptop — scenarios where a fixed data cap creates daily anxiety. Czech mobile data expensive at €3-4/GB locally — eSIM at $0.95/GB offers comparable or better value.
