I had purchased a Philips c20 mobile phone about 6 months back. It contains the key features like phone book list, alarm clock, voice mail, Pin No., storage for messages in archive, stop watch and watch, biocalender, user friendly style and design with clear recipient of signals but in some areas I have to face a sound problem with less efficient battery backup. So, I can say that this phone has average features, which does not go with its price.
