Does my EastESIM work reliably on China's High-Speed Trains (Gaotie) for continuous connectivity?

Generally, yes, your EastESIM will provide good 4G/5G connectivity while traveling on China's impressive High-Speed Trains (Gaotie) between major cities like Beijing and Shanghai. This allows you to stay productive or entertained during your journey. However, it's common for the signal to experience brief interruptions or cut out entirely when the train passes through long tunnels or navigates mountainous regions. We recommend downloading any large files or entertainment beforehand for a seamless experience during these short signal drops.
