If you have managed to get an unlock code from your service provider but no instructions on how to enter it into your nokia mobile cell phone then this page is for you... hopefully :)
What you need to do:
1. Either ring up your service provider (Vodafone, Optus, Three, Telsta) or go onto their unlock website and quote your IMEI number and perhaps a few other details. Some providers will charge you a fee to release this information.
2. The code your recieve will be 15 digits long.
3. Start up your phone with no SIM card in it. The phone should start and take you to the main screen / home screen (you can look around the phone but can't make calls/go on the internet etc)
4. Now as if you are entering a phone number type (from home screen):
#pw+your 15 digit number+1#
For example your 15 digit number is: 123456789012345
You would enter: #pw+123456789012345+1#
Now to get a 'p" you will have to press '7' a number of times, to get a 'w' you will need to press '9' a number of times etc, just as if you were typing a text message.
This is what I did. If it doesn't work for you then I'm sorry you will need to find out some other instructions, I don't know how to do unlock your phone specifically.
Have fun and thank you to the web page I found this on originally :)
