The Wearsafe Tag SOS button is designed to work with your phone 24/7, so that no matter when you need to send a Red Alert or Check-in, it’s ready to go. If you leave it behind for a few days, it will reach out to your phone when they're back in Bluetooth range. If you plan to leave your Tag unused for more than a week, we recommend removing the battery. As soon as the Tag SOS button has power again, it will reach out to your phone and be able to start alerts again.
