DataESIM typically delivers 4G signal at railway stations along the Laos-China Railway (LCR), including key hubs like Vang Vieng and Boten. However, due to the extensive tunneling required for the high-speed route between Vientiane and Luang Prabang, passengers should anticipate intermittent signal loss within these enclosed sections. Coverage will generally resume upon exiting tunnels, but continuous connectivity for bandwidth-intensive tasks may be challenging during tunnel transit.
