My 8310 was working fine with no problems, then in the morning as I turned
the phone back on it prompted me with the Insert Sim message, thinking it
was just being cranky I gave the sim card and the conductors a clean with a
dry cloth thinking this would sort the problem. But the phone still refuses
to see it. I have tried another sim in the phone and get the same error and
if I try the sim cards in another phone they work fine.

Does anyone know if it is possible to fix this problem or is simply a better
option to buy another phone rather than waste money on getting it fixed?

Thanks in advance for any advice.
