This question has been asked many many times about the N97 and other models.
The cause is that you have used your sim in an older phone that stores a limited amount of messages on the sim card. To solve the problem all you need to do is:
Menu > Messaging > Options > Sim Messages
Delete all of the old messages you find in that menu.
