Yes, absolutely. Czechia has an excellent, modern network. You will have a strong signal on the RegioJet or České dráhy (CD) trains between cities. Crucially, you will also have a continuous 4G/5G signal inside the Prague Metro (subway) stations and tunnels, allowing you to use Google Maps or Bolt (ride-hailing) without interruption.
