Can Find My or Lost Mode Be Bypassed on a Stolen iPhone?

Not easily in any legitimate way. If Find My and Activation Lock remain tied to your Apple Account, a stolen iPhone is much harder to reactivate or resell as a normal phone.

What Thieves Usually Try Instead

1. Phishing messages to trick you into entering your Apple Account password.
2. Pressure tactics asking you to remove the device from your account.
3. Selling the phone for parts if they cannot unlock it.

What Lost Mode Really Does

1. Locks the phone remotely.
2. Displays a message and contact number if you choose.
3. Keeps the device associated with your account for tracking and protection.

What You Should Do

1. Keep the device in your account.
2. Never share verification codes or account credentials.
3. Change passwords and notify your carrier if necessary.
