How to send a message to the lost Apple phone,

If the equipment is stolen, it is recommended to call the police at the first time, and they are obliged to assist you in handling it.

You can also recall whether you have turned on the settings-iCloud-to find my iphone. If so, I suggest that you can download and find the iphone through the app store to perform a function of locating and erasing data, but this function will only receive relevant instructions when the device is online.

Hope to adopt, thank you.
