In case of any emergency, you will only have to press the SOS button on the Widget or the power button x5, it will work without coverage, in lock and anywhere in the world. Safy will automatically record what happens to you, locate you and call your security group sending them the video along with your location in real time. Your SOS will be protected so that you can access it from the web (safy.app) if your device is stolen. -------------------------------------------------------------------
