Tu-ka S: that's what they call a cell phone!

Released in November 2004, Tu-Ka S cell phone impresses you with its extreme simplicity. By the way, S in its name stands for simplified, while Tu-Ka is a name of wireless carrier, a unit of KDDI group that targets non-3G users and runs on 2G PDC network.

This phone does not have any screen, address book or any other features we got used to have on modern cell phone. The only feature it has is voice communication. That's it.

Of course, there is a reason why Kyocera came up with such device. It aims senior citizens that prefer devices with simple interface and easy-to-see buttons. Believe it or not, the phone proved to be popular enough to help Tu-Ka to stop the tendency of customers fleeing from the carrier. Actually, Tu-Ka even managed to do some new net additions in recent months.

Tu-Ka S specifications:

• Weight - 87g
• Talk time - 240 minutes
• Stand-by time - 840 hours
