iOS and iPadOS devices without a cellular connection use only Wi-Fi for Location Services (if a Wi-Fi network is available). Some third-party apps rely on a Wi-Fi connection for region monitoring. If a device is passcode locked, this feature may be limited or inaccurate.
Improve GPS accuracy
GPS accuracy depends on the number of visible GPS satellites. Locating all visible satellites can take several minutes, with accuracy gradually increasing over time. To improve GPS accuracy:
- Make sure that you've set the date, time, and time zone correctly on the device in Settings > General > Date & Time. If possible, use Set Automatically.
- Keep a clear view in several directions. Walls, vehicle roofs, tall buildings, mountains, and other obstructions can block line of sight to GPS satellites. When this happens, your device uses Wi-Fi or cellular networks to determine your position until the GPS satellites are visible again.
