Ask a question:


4rd alternative method

Solution

This is the 4rd and last alternative method to enter the sim unlock codes in your Samsung Mobile.
If this method also doesn't work and you tried all other alternatives please carefully read the information at the bottom of this article.
 

  1. Turn off the Wi-Fi on your phone and then turn device ON without SIM card
  2. Once it's on go to phone dial screen and DIAL: *7465625*638*#
    it will bring you to the NETWORK LOCK screen.
  3. In the MCC/MNC field enter the code for the service provider your phone is originally from (eg 31026 for T-Mobile USA)

    check here for list of codes: http://en.wikipedia.org/wiki/Mobile_Network_Code
    *If your network has more than one mcc/mnc please try all of them
  4. In CONTROL KEY field enter the Network UNLOCK code
  5. Hit OK
  6. You should get a message: LOCK SUCCESSFUL

Power phone down, insert SIM card you want your phone to work with and power on.

 

If this solution also fails for your phone it means the phone has a problem with the firmware. Some firmwares (especially from I317(m), I337(m) ) have a bug and don't accept the original codes. The only solutions for this phone is to change the firmware. Flashing the firmware is a bit more advanced but our support can help with this and provide you step-by-step instructions.
