How to use Android's emergency satellite texting if you lose cell signal

If you have an Android phone, you might have noticed an “Emergency SOS” feature. This feature, turned on by default, lets you call for help in an emergency, but it does require a cellular or Wi-Fi connection. If you press your power button five times, your phone will immediately dial 911, send a message with your location to preselected contacts, and record a video. 

You can choose which of these actions your phone does in the Emergency SOS settings. Be warned, if you try to press the power button five times to get to the settings for this feature, the actual process will begin and you’ll only have a few seconds to stop it. If you want to set it up, find it in your phone’s settings menu.
