After then started something limited 4GB and after that 128kbps and not going calls every time when I tried to call every time it says all lines are busy now try after some time.and same situation on msgs also sending failed. infact urjent situation my family calling me but I dnt receive call also. I dnt understanding why it is going like this suddenly it is showing emergency calls only and network also up and down.
