LiveLife GPS Mobile Alarm. The LiveLife 4GX Mobile Alarm allows seniors to maintain their independence and remain active, while also keeping them safe. The stylish waterproof pendant uses the same cellular phone technology as a mobile phone, without any over-complicated features. Up to six emergency contacts can be stored in the device, which uses the best available 4GX/4G mobile network to notify all emergency contacts, with the push of a button, if a senior loved one is in need of help. A built-in GPS tracker allows for easy location, and the device also has a hands-free speaker-phone mode for both incoming and outgoing communication.
