Travelers to China cannot use their home phone numbers and data plans due to network incompatibility

International travelers visiting China face a critical connectivity problem: their home country SIM cards don't work on Chinese networks, leaving them without reliable phone service or data access during their trip. Current solutions like traditional roaming are prohibitively expensive, and finding compatible eSIM providers that actually work in China is confusing and time-consuming. Travelers desperately search for working alternatives because being unreachable abroad creates safety, navigation, and business continuity risks.
