How to prevent Apple's mobile phone from being lost

Positioning needs to meet certain conditions:

1, the equipment is in the boot state, and the machine has not been brushed;

2. Before I lost it, I logged in with my apple id account on the device's icloud and turned on the "Find My iPhone" function;

3. The device has turned on the GPS service, but the mobile cellular data has not been turned on.

You need to meet the above three conditions at the same time, and then you can open/on the computer. Before logging in, you lose the apple id account on the device, and there is a "find my iPhone" in it. Click Locate to find, or you can set the lost device as lost device, remotely erase the data on the mobile phone, and so on.
