Hi,
I am using a nokia 6600 phone and few days ago i checked in for using lock code and therefore applied a lock code. Now i forget that code and can't use my other sim cards due to this code except the one which i used while entering the lock code. Pls help me from this problem. How can i overcome it and use my other sim cards.
Thankyou.
