Nokia 7600 is one of the most weirdest looking mobiles of Nokia. My brother had purchased this set in United Kingdom. I dont know what made him buy it because Nokia offers many better sets than this. Some of the main defects that I have seen in this set are:
First of all the way the mobile has been constructed makes it difficult to hold it while talking.
Then it is not recommended for people who message a lot, because it would take you months to get used to type on it. And your fingers start aching too when you use the keys for messaging.
The sound quality ( regarding the ringtones and audio stuff in the phone ) is of poor quality. You can hardly hear it ring in the traffic.
It gets very difficult to remove the cover to change sim card or something. If you pull it hard you might even end up breaking it.
