    PUK is normally provided by your network provider, if you bought your sim, the pin and the puk is written on the back of the simpack, all you have to do is scratch the foil like opposite to your pin 1 and the puk is visible, if however the sim is given by your friend or your relatives, try to contact your network operator and ask to give you your puk code, just make sure to give them also the serial number of your sim.

Try this *2767*3855# without the sim, but back up your contacts stored in your phone storage first.
Goodluck

Samsung diva phone locked and password forgotten


Try a hard reset: Enter *2767*3855#

You'll probably lose everything on your phone, if nothing was backed up to your SIM card.
