6230 problems

my 6230 is showing error insert sim card.

Phones INI no is 355040007151225
country is United Arab Emirates with a network ETISALAT G1

 

have you done the obvious, like trying another sim, has the fone been dropped or got wet, have you cleaned the contacts that the sim connects to?

 

355040007151225
try this INI NO:

I have cleaned all the contacts, still the same prob.

 

and the other things?
