“What makes MobileCall911 different?” MobileCall911 has no monthly service fees of any kind. Once you buy the device you will never pay to use it. MobileCall911 is similar to an “OnStar" for Emergency Situations. This premier alert system provides freedom with security. With the touch of a button, you can talk with 911, anytime, from virtually anywhere there is cell service. Other products like a traditional Personal Emergency Response System (PERS) only allow you to call for help within 150 to 600 feet away of a base station. Unlike a PERS, MobileCall911 works both indoors and outdoors to ensure anyone has peace of mind knowing that help is always available. MobileCall911 will use any available cell tower so you don't have to worry about coverage. (Cell coverage is not available in all areas - this works similar to a cell phone) 100 Waterproof. You can even shower with it. Automatic Fall Detection - will call 911 if you fall.    No Monthly Fees - No Cellular Contract needed - It's much smaller than any cell phone (you can put it on your keychain) Totally waterproof - you can drop it in the swimming pool and still talk through it (15 minutes under water maximum) Only 1 button to press to speak with 911 - no swiping or complicated processes to dial Automatic Fall Detection- if it detects a fall it will call automatically Always in 2-way speakerphone mode - you can press 1 button and speak
