Is mobile signal and navigation reliable inside Xiaolangdi Dam?

[Direct conclusion] Open areas usually have full signal; navigation works but follow signs in big parks. Key points to keep in mind: 1. Download offline maps; elders who stray can still be located. 2. Signal: Most areas have 4G/5G. 3. Navigation: Maps are accurate on main paths; remote trails may drift, trust on-site signs. 4. Offline: Cache offline maps and mark meet-up points so you never lose the way. Note: Double check the meeting time and meeting point one day before the trip.
