Nokia cellphones come with PINs.
DCT4 is the name of the generation of phones that were released by Nokia from 2003 to 2008. It is also the name of a generation of platform software and security technology used in Nokia cellphones. Nokia phone models that were made with the DCT4 code include the Nokia 5000, Nokia 3230 smartphone, Nokia 3200, Nokia 1600 and Nokia 1100.
PIN/PUK Codes
The security on a Nokia phone is provided by PIN codes. The personal identification number or PIN code of your subscriber identity module or SIM card consists of a four-to-eight-digit code that is meant to protect your SIM, which holds your cellphone number and in some instances your contacts and phone number list. If you incorrectly enter the PIN three times in a row, the phone will lock and you will need to use the personal unblocking key code, or PUK to unlock it. The PUK is an eight-digit code that you may be able to get from your cellphone network provider.
Lock Codes
The default lock or PIN code of a Nokia phone is 12345. It's a good idea to change the lock code once you purchase your phone to prevent someone from using it without your permission. When you see an error message from incorrectly entering the code three times, turn off the phone and wait 15 minutes, then turn it back on again.
Restriction Code
If you attempt to use a new SIM card, either to change your phone number or to change your cellular phone network provider, you may get the message "Enter restriction code." This is because the phone has been locked. A locked Nokia DCT4 phone can only be used with the network of the cellphone provider that you purchased it from.
Unlocking DCT4
Changing the subscriber identity module or SIM card of the phone will not take it off the company's network. You can unlock your DCT4 Nokia phone and change the SIM card to use a different network or a different phone number with a local area code when you are visiting another state or country to avoid huge roaming fees. You may be able to contact Nokia support to get your SIM unlocked or you can get the codes for unlocking your particular model of Nokia cellphone online with a free Nokia SIM unlock code.
