Will my eSIM work on the high-speed 'RegioJet' or 'České dráhy' train services between Prague and Brno?

Yes, our eSIMs utilize the robust networks of O2 and Vodafone, which provide extensive coverage along major rail corridors in Czechia. While brief interruptions can occur in tunnels or very remote areas, you can expect reliable 4G/LTE and often 5G connectivity for the majority of your journey, ensuring you remain productive while in transit.
