My nokia 6300 do not accept any security code and give error code?

You should have received a paper with the security code when you bought the SIM card (and your phone).
If you lost the security code, get the SIM card replaced at the shop.

Restriction code and network unlock code is same..Nokia Phone asks restriction code..If your Nokia Locked to network and you are trying to inserting other GSM Network sim card it will display the message "Enter Restriction Code" Without unlocking it you cannot use other GSM Network sim card.After Unlock it you can use only gsm sim card...
You can get the Restriction code from service provider,but they ask to wait for many days or months.
So you can get the Restriction code for Nokia 6300 easily from the site
Mobile-unlocker.com/nokia-6300/rs2wp9/ and unlock it easily...To enter the code you can follow the instructions below:

The CODE you need to enter is the unique unlock code for your Nokia 6300

Phone Security Code:
This locks the handset, as opposed to the sim card. You can also set some handsets to only accept a “new” sim if the phone security code is entered. To reset it, you need the Master code code:
Master Reset Code
Sometimes known as the Master Code, this allows you to unlock a handset if you have entered the Security Code wrongly too many times.
The default security code for Nokia is 12345

IMEI: 358647011866197
Master code: 4154001611
Take your SIM card out first.
This is the code needed to reset the Security code, nothing else, and it’s for your phone only. You type in the security codes (anything) until the phone request the Master code; when it does, leave your phone still, don’t use it for 15 minutes, then type in the Master code.
