The Samsung SGH J600 is designed to work on a GSM network. GSM is an acronym for Global System for Mobile communication. Phones that rely on GSM technology require a SIM card, which is a type of portable memory chip that allows a mobile phone to connect to a particular wireless carrier. If your Samsung SGH J600 phone is locked, it means that the phone can only be used with a SIM card issued by your current service provider. Unlocking a Samsung SGH J600 lets you use the phone with a SIM card issued by any GSM network.

Contact the wireless carrier that issued the SIM card you just removed from the phone. The provider's logo should be printed on the back of the card. Ask the carrier's customer service representative to provide a SIM unlock code for the phone. If certain service terms are satisfied, many GSM carriers will provide unlock codes for phones branded for use on their network at no charge. The customer service representative will ask you for the phone's IMEI number. If you are unable to obtain an unlock code from your carrier, go to Step 5; otherwise, move on to Step 6.
Go to Unlockitnow.com, Globalunlock.com or Unlocktotalk.com. These are commercial SIM code-unlocking services. On the website, you will be prompted to input the phone's brand (enter "Samsung"), model number (enter "J600"), your current wireless carrier and the phone's IMEI number. Place an order to purchase a SIM unlock code for the phone.
Slide out the phone's keypad and turn on the phone.
Press "#0111*" on the phone's keypad and then carefully enter the unlock code you obtained in Step 4 or 5. Press "#." If you entered the unlock code correctly, you will see the message, "Network Lock Deactivated" on the phone's display.
