Do I need EastESIM data for using KTM trains in Malaysia?

Yes, having reliable data from EastESIM is incredibly helpful for navigating Malaysia's KTM (Keretapi Tanah Melayu) train network. While you can buy tickets at stations, using data allows you to check train schedules, track live arrivals, and even book e-tickets through apps for routes between cities like Kuala Lumpur and Penang (via Butterworth). It ensures a smoother journey, especially when planning connections or dealing with unexpected delays, keeping you informed every step of the way.
