Nokia 3110 Classic
Restart during Browsing

I am using Nokia 3110 Classic and suffering the problem of restart during the Browsing.

Sometimes, browsing is very smooth but most of the times i really anoy from its restarting problem. I don't know how to overcome this problem.

By removing battery againg and again, the phone comes to the normal stage.

If anyone can help me out of this problem, pls do it.
