To fix the "off network" or "no location found" error on your new iPhone 18 Pro Max when viewing others, check your System Services location toggle, as it often gets missed during device setups.
1. Enable "Share My Location" in System Services
Even if your general location sharing is on, a deeper system toggle might be turned off.
- Open Settings.
- Go to Privacy & Security, then tap Location Services.
- Scroll all the way to the bottom and tap System Services.
- Look for Share My Location and turn it ON.
2. Verify "Find My" Permissions
- Go back to Settings > Privacy & Security > Location Services.
- Tap on Find My.
- Ensure access is set to While Using the App and that Precise Location is toggled ON.
