The Primo 366 features a 5.8 cm TFT display and a spacious, illuminated keyboard. It includes all the functions one would expect from a classic mobile phone: Bluetooth, camera, FM radio, flashlight, alarm function, clock, and calculator. A small innovation is that the actual SOS button on the back of the phone, if not needed, serves as a direct speakerphone button. The phone book can store up to 250 entries, and there is even an ICE (In Case of Emergency) function available. This allows you to store all important information regarding blood type, medical conditions, and medications that could be life-saving in the event of an accident. Through the SOS function, five phone numbers can be saved for emergency calls.
