Could be dirty SIM contacts, try removing it and cleaning them thoroughly,
make sure the SIM is making good contact, I don't know the 8310 but some
phones use a clip to hold the SIM in place, check this is in good
condition.

Take out the SIM card and cut and stick a post-it note on the back of it.
The extra width is enough to push the SIM card down onto the contacts that
little bit harder, ensuring a better contact with the SIM connections in the
phone.
