Change the PIN number

This varies a bit, depending on brand of cell phone. I gather you are referring to the pin code for the SIM card.

Hi. i fprget my pin code of my cell phone can you help me please

First ask your service provider for the PUK number. after getting the PUK number, go to security settings and choose change PIN, it will ask for old PIN number, try a random number and then it will show 'sim blocked', please insert PUK number.
Insert the PUK you got from your operator and then you will be able to change your PIN.

Unless it has been changed for some reason. The pin should be the last 4 numbers of your phone number.

Forget my nokia n73 lock code

If you need the SIM Pin number to switch the phone on, then you have to enter any Pin number 4/5 times, then the phone will request a PUK number. This number was on the plastic card that your SIM card was attached to. If you don't have it, only your Network Service Provider can supply it to you.

If it's the Security code you need, to get into certain settings IE. Erasing received calls, missed calls, timers etc... The Nokia default is 12345 if you didn't change it, but if you did change it and you've forgotten it, let me know, I'll tell you how to retrieve it.

The IMEI number doesn't have anything to do with the SIM Pin number. It is used to identify, track, and Blacklist your phone.

Finding phone lock code

If it's the SIM pin number you need to start your phone, just put any pin number until the phone request a PUK number. If you don't have one you can get it from your service provider.
If it's the Security number you need, to change certain settings in your phone, and to prevent anyone else using your phone with a different SIM card, then I need the IMEI number to give you the Master Code.
