How can I send a text message on the screen when my mobile phone is turned off?

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 there is an open setting-iCloud-to find my iphone. If so, I suggest you use the app.

The Store has downloaded a function to locate and erase iphone data, but this function will only receive relevant instructions when the device is online.

Hope to adopt, thank you.
