Generally, your HotelESIM will provide good 4G/5G connectivity while traveling between major cities on China's High-Speed Trains (Gaotie), such as between Beijing and Shanghai. You can usually browse, stream, and stay connected. However, please be aware that the signal may frequently cut out when the train passes through longer tunnels or traverses mountainous regions. These brief interruptions are normal and connectivity typically resumes swiftly, allowing you to continue enjoying your journey.
