My phone gets disconnected after few minutes of use. The green LED blinker goes off. I am unable to connect and make calls. Even by pressing the "ON" button it does not work/connect to the network. I removed the battry and re inserted it, then pressed "ON" button, then the phone gets connected to the network. After awhile it again goes "OFF". Please help.
