There should be a switch on the side of the memory card, which says 'LOCK' on one end, and 'UNLOCK' on the other end. Switch it to UNLOCK. If this fails, contact first your network provider(Orange, Voadfone...). If they cannot help, you need to contact Nokia. If this fails, contact Kingston. This will help.

when transferring the micro sd to the pc from your mobile do you have to use an adapter? there is a lock on the sd adapter that when pushed down it wont let you edit your anything on your card.
is this the issue you are experiencing?
