Based on the provided reference, you don't directly "add a device" to Find My iPhone (now just called "Find My"). Instead, you can share your location with someone using iCloud so they can see your location.
Here's how you can share your location with someone using Find My:
- On your iPhone, open the Find My app.
- Tap on the People tab.
- Tap Start Sharing Location.
- Choose a contact using iCloud on their device.
- Tap Send.
- Choose how long you want to share your location: Share for One Hour, Share Until End of Day, or Share Indefinitely.
This will send an invitation to the selected contact, allowing them to see your location in their Find My app.
Important Considerations:
- This functionality is for sharing your location with another person. It doesn't involve adding a new device to your account directly. Each device connected to your Apple ID will automatically appear in your Find My app.
- To add a device you own to Find My, ensure you are signed in to iCloud on that device with the same Apple ID as your iPhone and that Find My is enabled in the device's iCloud settings.
