I love that we can use it for everything from doctor appointments through after hours emergencies! It makes our life so much easier as an EMT/Paramedic when you have patients or students who need help but may be too sick themselves (especially if they're unconscious) just by calling them at home instead trying call their regular number which might not even answer!! This has helped us make sure everyone's OK during these times where things could go wrong very quickly especially here out west due time difference wise between California & Nevada sometimes there isn't enough coverage available until 3am PST - 4 am MST depending upon area location etc..
