How I know my phone location

You can check where your phone is using another device if 'Find My' is turned on and your other devices are signed in with the same Apple ID as your iPhone.

On another Apple device, open 'Find My' and press 'Devices'.

On a computer, go to https://www.icloud.com and sign in using the same Apple ID that's on your iPhone. Then, press 'Find iPhone'.

If you enabled Find My on the phone you can either use Find My on another device or log in to https://icloud.com/find.
