The Swissvoice SV39 mobile phone comes in a rubberised casing to protect it from dust and bumps and it can also survive falling into water. For noisy environments, or users with hearing problems, the device has both a vibration setting and a loud ring.
One button push can select five stored numbers sequentially. The SV39 also has a 2-inch display, Bluetooth, a speaker function, a built-in flashlight and a radio. Available now, it costs 100 euros.
