DataESIM generally delivers excellent 4G/5G connectivity on China's High-Speed Trains (Gaotie) while traversing between major urban centers like Beijing and Shanghai. This allows for productive remote work, streaming, and continuous communication. However, anticipate brief interruptions in signal when the train enters extended tunnels or passes through mountainous regions, which is a common characteristic of high-speed rail networks globally. Overall, performance remains robust for most of the journey.
