When you rely on your phones for nearly everything, the idea of being disconnected from the outside world is stressful at the least and terrifying at the most.
What can you do if you lose your iPhone or if it is stolen? Be prepared. Use a password, enable Find My iPhone.
When viewing the device’s location, select Actions at the bottom of the screen followed by Lost Mode. You’ll be asked to enter a phone number and a message that will be displayed on the lock screen for whoever has your device to get it back to you.
Otherwise, remotely wipe the iPhone.
