Nokia 6270 Network Detection problem

[deepsharma82]

Dear Forum Users.

I am using my Nokia 6270 since 2 yrs, and its working perfectly fine.
But two days back, it automatically lost the network. I had just talked to my friend, and after five minutes it lost the signal. Since i was travelling, i thought its a network loss, but then I realized its gone permanently.
My phone has not fallen even.

Whats worst is that the network is detected sometimes for 1 or two minutes, but then automatically its lost.
I tried to search for manual network selection, there also no network is found.
My sim card is working fine in other mobiles.
Please help me, I am stucked

Thanks.

Deep
