Your phone is asking for a code because it is locked to only work with one phone company. If your new sim is from a different company, you can request the unlock code from your old company, they may or may not give it to you (tmobile usually does, ATT/Cingular usually doesn't). The other option is to use a unlocking service, you can find plenty on ebay. If you didn't change phone companies, your new sim card is most likely bad, have your phone company send you another one.

Samsung GT-S5233 ..my simcard is locked. i have the puk number but where to insert it.


Hello

Since your simcard is locked,insert your sim card into the phone and turn on the phone,allow it to boot up.

A message will appear on your screen saying "Sim card blocked please enter PUK (Pin Unblocking Key)..type in the PUK number this number will reset your pin code and you will be asked to create a new 4 digit pin for you simcard.

Good luck

3. When Incorrect SIM error comes up, type *#9998*3323#.
4. White screen will appear with an exit option. Press the right softkey.
5. From the menu that appears, select the Malloc Fail option. This will rebootthe phone and the normal service screens will appear.
6. Type *0141# and then press the green call key. "Personalization"or "Personalized" will appear.
7. Turn off your phone and put the original SIM back in.
8. Turn on your phone. You will receive a prompt to enter a password.
