Hi,SIM crash means your electronic data on the sim can not be reachable any more..
First try it on another phone,if problem continues ask your service provider to replace the Sim card..

There is a physical issue with your Sim card reading: Sim may have been slightly dislodged if you accidentally dropped or subjected your mobile to vibration: in most case, just remove the battery AND Sim for a few minutes and carefully re-install both Sim (make sure it fits squarely in the socket/cradle) and Battery and Cover. It should reset the phone.
Hope it helps!

There's only one USB port on the c600

hi, don't panic! You mobile phone is fine, problem is with the sim card. Try inserting sim card in some other phone (Try Nokia) it will definitely work. If you dont hav different mobile phone then carry your sim card to customer care and they will change the same and give you duplicate sim. They may charge something for duplicate sim card.

If you press F12 during bootup, you should get the boot menu. Run the hard disk diagnostic. If the hard disk is bad, you will get a DST Short Test Error code.

Replacing the hard disk in a D600 is a piece of cake though so if you need a new HD, it's easy to do. The tedious work will come afterward.

do you have enter a password for your sim?if not,try to ask for a new sim..or you try enter 0000..hope this help..
