Invalid sim card

While switching on my nokia 7610, I obtained the following message:Invalid sim card. I have to switch off again and re-switch on. Why?

The phone works normally on the network. It occurs rarely.

take your sim card out and give it a clean
may be a bit of dust getting in the way of the connectors
