D600 water damaged, turns on but?

Accidentally machine washed my samsung D600, but after a thourgh drying out it charged up fine and turns on ok and seems completely dryed out. problem is i get a "insert sim" message/screen which i'm unable to get past. The sim which was in the phone when washed works fine in other phones but not the 600, whilst other perfectly working sims also fail in 600. Can anyone help with this? - Surely if i could purchase the right spare (some part responsible for reading the sim?) i could repair this myself?!
