780X
Waterproof and easy to use, the 780X simplifies your security. Three large, labeled keys make it easy to call people you trust without navigating through menus or calendars. It also offers great safety features like an assist button and a safety timer that sends an alert text message with your GPS location if you need help.

simplified keyboard
  Designed for seniors, the 780X features a simplified keypad and calls up to 3 contacts. Users can receive but not send text messages. When a Doro user reads a text message, the sender will receive a "message opened" notification. The keypad consists of 3 main keys which, once programmed, will correspond to saved contacts. Next to each key, you can type the name of a saved contact to avoid confusion. Then there are call start and end keys, a right, left, up, and down selection key, and two more navigation keys.
