It’s fun to have a Nokia 5110, its a cool mobile...it supports almost all necessary features with an acceptable price....the most important feature is its easy navigation key..with a single navi key, we control all the operations including the calling, end of a call, managing menu etc..menu includes calculator and alarm with easily understanding interface which is common to almost all nokia phones...the batterise required to work the phone in vibrational mode is not a standard accessory....
