The ETravelSim Sri Lanka eSIM works at the major train stations along the Kandy-to-Ella route including Kandy, Peradeniya, Hatton, Nanu Oya, Haputale, and Ella, with intermittent signal along the scenic stretches between stations. This is normal across every Sri Lankan carrier — the famous tea-country sections pass through long mountain tunnels and deep valleys where signal naturally drops. Most travelers prefer it that way.
