What if Apple turns on the lost mode and sends a message saying that someone wants to unlock it?

You can swipe your card when the IPhone is in lost mode, but you will be asked to enter the password of Apple ID to activate it. If you don't know the password of Apple ID, the mobile phone can't be used.

Lost mode

Apple's "Find My iPhone" function is specifically aimed at stolen iPhones. This application is very practical. It can locate the location of your iPhone on the satellite map, send messages remotely, remotely lock (lost mode) or remotely erase the information in the iPhone, and also remotely send sounds to the iPhone. Even if you can't find the lost iPhone, you can delete it.

The private information in the computer will minimize the loss. The following figure shows the result of enabling "Lost Mode" remotely on the computer.

When the mobile phone has a network, after receiving the signal of lost mode, there will be the following prompt. The information in the middle is input by the owner when he starts the lost mode, and there will be some differences, but at this time, the mobile phone is locked remotely.

After executing the lost mode command, the phone will display the information set by the owner. Nothing can be done except dial the set number. You need to enter your Apple account and screen lock password to unlock it. If someone else enters DFU to refresh the computer reinstallation system, after the installation is over and the iPhone restarts, the device must be connected to the Apple server for activation. If the Find My iPhone function is enabled on the iPhone before refreshing the computer, the Apple server requires that only the previous AppleID can be used to activate the device.
