Sounds like moisture. Check with your local dealer as they can easily tell you if it is water damage.

• PUK means "personal unlocking key" .
  The PUK code is asked if you enter a wrong pin 3 times.
  You need to call your phone service company, they can retrieve the puk code from a database
  for free.
  In your case you need to contact your SIM card phone provider technical support to unlock the SIM.
  The PIN and PUK are related to the SIM card, not to the phone.
  If you replace the SIM card with a different one, then the phone should not ask for the PUK anymore.
  Your rating is highly appreciated on this matter.

Your SIM card is not being read anymore due to a number of reasons.
Try rubbing the SIM card with a clean smooth dry cloth and then insert it again.
If that doesnt work, your SIM might be damaged, take it to your network provider and they will replace it, hopefully with your same phone number.

it could be that the contacts between the phone and the sim card are dirty and therefore you will get the error code. take the battery out and remove the sim card take a q-tip with some rubbing alchohol and clean the contact on sim card and the phone itself make sure not to use alot of alchohol. let them air dry then re-insert the sim and battery this should do the trick. the error warning should go away and the phone will be abale to receive the contact info from gthe sim card.. please rate this

WWATER GO INSIDE TE PHONE REMOVE BATTERY BLOW IT

The puk code is sim card spesific it comes with the sim card when you get it or you can get it by calling your phone service provider of the sim card to get the puk code.
if you have entered the puk code wrong too many times you will make the sim card useless and you will have to contact your phone service provider for a new sim card, it will probably cost.
