Here's how I choose a good mobile phone.First, check for a clear voice quality. This is the basic functionality of the phone, which a lot of people overlook. The phone is of no use if you cannot hear the voice of a caller when you are driving down the highway. Secondly look for phone that has simple interface for navigation. If you have to do three menu selections just to type an SMS, it means the phone is of no good use. Another main thing to check is the battery life. Go for a battery that can last for a few days. Do not pay much attention to the “standby” battery life but look for one that gives good battery life during your normal day to day use. Nowadays Bluetooth is fast becoming a necessity than a luxury. Go for a phone that can connect instantly to any Bluetooth enabled phone and helps you transfer data, messages, images, videos etc for free
