Hi is your samsung c3530 mobile is asking for sim lock code once you insert your sim in it then it mean the phone is locked to some other network provider due to this it wont accept any other GSM sim until you unlock it ..You can easily unlock your phone through online providers like
MobileUnlockSolutions.com here they are rendering sim unlock code for all mobile models at reliable cost .You first check that whether the code is available for your country and network provider .If yes then pay for it and unlock the phone then freely use it with any GSM sim ....
