My phn was running fine until i entered into a roaming zone and it stopped showing the signals. at first i thought may be its because of the roaming but it shows the same thing at local number as-well.
I can recieve text msgs and can also send text msgs by typing in the no's, as I can't open the contacts and can't open the dialing screen. it shows a yellow mark where it used to show the signals. my phn is updated to win 6.5 proff.
plz help me and guide me how can i resolve this issue.
