Generally, yes, your eSIMAdventures plan will provide 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 connected, stream, or work en route. However, be aware that the signal may frequently cut out when the train passes through longer tunnels or traverses mountainous regions. For critical tasks, we recommend preparing offline content, but for most of your journey, you can expect solid connectivity.
