Hi,

Not sure if this has been done here yet but it I couldn't find it so here goes.

Got a Nokia DCT3 (3210, 3310, 3410 etc.) that needs unlocking or a DCT4 (3510 etc.)?

All you need is your Model, IMEI# (obtained by pressing *#06#) and your network and country. It's that simple.

once you have the codes (they will look like this #pw+0000000000+1#)
you will need to put them into your phone. And that's simple, take the SIM out and press the '#' key, to get the p,w & + you use the * key. when the last # has been put in the phone should say 'sim restriction off' and then reset, and voila you now have a fully unlocked phone that you didn't have to pay to unlock or hook upto a computer. (Please note that on Orange DCT3 you will get two codes and you will need to use both, DCT4 you'll get a list of 7 but you only need to use the last one)

You only get 5 attempts to get the code right, if after the fifth attempt it still hasn't worked only a cable unlock will be able to do it.

enjoy
