Will my eSIMFlyer e-SIM have internet on the Laos-China Railway?

While traveling on the modern Laos-China Railway (LCR), your eSIMFlyer connection will generally be strong at stations such as Vang Vieng and Boten. However, as the high-speed train traverses the mountainous terrain between Vientiane and Luang Prabang, expect intermittent signal drops inside the numerous tunnels. It's a fantastic journey, but plan for occasional offline moments. Download any necessary entertainment or work before boarding to stay productive during tunnel passages.
