When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security code then :- This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (security code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone. They should provide you with instructions on how to enter this code into the phone. Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.
You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country. This maybe a free service. The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services.Use Google and search for "Security unlocking code” companies in your area.

the same thing happened to me..you will have to contact your service provider and tell them what happened..they will give you/use a PUK code v(personal unlock key)
some info:Pincode stands for PERSONEL IDENTIFICATION NUMBER. It is the fourdigit number which is used to lock the phone. The phone will ask for the code when you switch on it.With out entering the correct pin code you can't access your phone.If you enter the pin code wrongly for a specified(normally 3)number of ties your sim will get locked.You can't use that sim in other phones also without unlocking it.PUK code (PERSONAL UNLOCK KEY)is used tounlock the sim card if it is blocked.PUK code is provided by the network operators.If the PUK code is entered 10 times wrongly the sim card gets permenantly blocked

The SIM unlock is something that's either enabled by yourself or by the network. It's not done by the manufacturer.
If you have the previous SIM card then you can disable the SIM lock by doing the following. In the main menu of the phone go into settings and then security settings. Under security settings select SIM lock and set that to disable. If it asks you for a password, then providing you've not changed the password, the default codes are 4 zeros or 8 zeros.
If this doesn't work or if you don't have access to the previous SIM card then you're going to have to contact Samsung to arrange a repair. As the phone is working as specified we would count this as an out of warranty repair so I'm afraid it is chargeable.
just give me the phones serial number........send it to firstname.lastname@example.org and i will try and give you the code for unlocking.
In newer phones: #*7337#
this step sometimes also works
If you have changed your phone password, change your password back to the default 8 zeros (00000000). 1a. NOTE (Modification here by my experience): Goto SETTINGS, SECURITY, then SIM LOCK and disable this before proceeding. 2. Put a SIM card that is from a network other than the one your phone is locked to 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 reboot the 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. 9. Type 8 zeros (00000000) (This is because the SIM LOCK mentioned earlier gets switched back on) 10. Completed. You have now unlocked your phone.
tested on e-series phones - may work on similar models but not sure
