Set up phone finding before a loss

Enable the built-in finding feature while you still have the phone, then confirm it appears in the right account.

What to do

First, check

Verify your Apple, Google or Samsung account and a screen lock.

Then

Turn on the applicable Find My or Find Hub settings and test that the device appears from another signed-in device.

If it’s not that simple

Correct linked account
Confirm the phone appears in the account you would use after loss.
Finding settings
Review the provider’s prerequisites on the handset.
Access without this handset
Prepare account recovery/backup verification so the missing device is not your only sign-in route.

Protect a phone before it is stolen

Good to know

Some offline options need a supported device and extra settings; test before relying on them.
