While traveling on the Laos-China Railway, your HotelESIM will generally provide 4G signal at the various stations, including popular stops like Vang Vieng and Boten. However, as the train traverses numerous tunnels between Vientiane and Luang Prabang, it is quite common for the connection to drop intermittently. We recommend downloading any essential content beforehand for uninterrupted entertainment.
