So I want to be brief. My 6 year old Nokia 6233 was not quite sure after it had hit something hard on the pavement, and the battery lasted just one day ... so I needed a worthy successor in the shape of a classic mobile phone's bars! So if you - like me - are looking for a mobile phone on which has got some real keys, which still however has a full range of functions and that you as well as purist - as I am ('m just calling and texting, occasionally make a snapshot and times good) - can serve is great advice with this C02-01. Typical NOKIA user interface, everything is instantly understood and set with a few simple steps. Battery lasts at least for me. One week. Call quality is very good. Bluetooth works in the car also excellent with the audio system. SMS writing is also great, thanks to a sufficiently large keys. A real classic phone in appealing design (black / chrome) and an extensive range of functions (one could thus also plan to the Internet, games, events, listen to the radio and so on ...) So can actually everything a smartfone also can ... but REAL KEYS and you do not ever somehow wipe over the screen and press ... so clear buy tip for all SMARTFONEVERWEIGERER at a fair price!
