mobile-review.com has an indepth review of the Nokia N93.

This handset has no problems with signal reception, voice of interlocutor is clear, just like your own. Volume of 64-tone polyphonic ring tone is average, but in case you choose mp3 file as ring tone, polyphony does not matter that much. Vibrating alert is slightly lower than average, sometimes you may miss a call due to that.

As for video recording, its resolution – this model is best on the market once it will be released, same goes for photo quality, but here difference in photos when compared to Sony Ericsson K790/K800 is insignificant. You will be able to find out more in our stand-alone material, that will be dedicated to photo-part of Nokia N93.
