When traveling on the Laos-China Railway (LCR), eSIM Routes generally provides 4G signal at key stations like Vang Vieng and Boten. However, given the numerous tunnels between Vientiane and Luang Prabang, you should anticipate intermittent signal drops while the train is in motion through these sections. Our service aims to keep you connected where possible, allowing you to plan your next steps during station stops and open stretches.
