Yes, for most of the journey. You will have a strong, stable 4G/5G signal for the majority of your scenic train ride. However, please be aware that on routes like the Glacier Express or Bernina Express, the train passes through numerous long mountain tunnels. It is normal to lose signal inside these tunnels, but it will reconnect instantly once you are out.
