The One Touch alarm is a personal monitoring system, which unlike many traditional services allows the wearer to travel far outside their home. It operates using the mobile phone network and allows the end user to continue living at home without any restrictions. The One Touch personal alarm uses a roaming SIM, so is not restricted to one mobile phone network. Therefore, there is less risk of the personal alarm being out of signal in an emergency, as the device will use whichever mobile signal is the strongest. Unlike a mobile, the personal alarm calls up to 3 pre-programmed emergency contacts simultaneously. When one answers, the others are informed that the call has been taken.
