» Unlocking DCT3


If you want to unlock one of these Nokia phones:
2100, 3210, ,3310, 3330, 3410, 402, 5110, 5210, 5510, 6110, 6150, 6210, 6250, 7110, 8210, 8250, 8850, 8890

To calculate the correct code you will need to input two pieces of information:

1. The handsets IMEI number, this is a 15 digit serial number that can be found under the battery. It can also be displayed by typing the code *#06# into your phone.

2. You need to know what network your handset is locked to. Each network has its own MCC+MNC (Mobile Country Code + Mobile Network Code) For UK networks you these codes are:
Network MCC+MNC
Orange: 23433
O2 (BT Cellnet): 23410
Vodafone: 23415
T-Mobile: 23430
Virgin: 23430
Tesco: 23410

STEP1: Once you have these two pieces of information download DCT3 Codes Client V1.3 Here Extract then enter them into the relevant fields. also you could try this online calculator here

The site or the program will generate code , something like those below:

#pw+3789067026+1#


STEP2: Now enter the code into your phone with NO sim card in! Choose the top code if that dont work choose the bottom one.

To access "p" just press "*" three times within one second. To access "w" press "*" four times within one second.
To access button "+" you have to press twice "*" within less than a second.

If successful you will see the message 'Phone restriction off' (if not you will get a 'code error' message).

Now your phone should be unlocked very easy :)

Important!!

If the handset is still locked after you have seen the 'Phone restriction off' message then you must also enter a 2nd code!

This lock is calculated using a value called GID1. In the UK depending on your network you may need to enter a 2nd code:

Orange and Virgin ALWAYS require 2 codes to be entered
T-mobile NEVER require 2 codes
O2 and Vodafone SOMETIMES require 2 codes

Below is a list of all the GID1's values for UK networks, you can use these values to calculate lock 2. (These are HEX values):
GID1's
UK Vodafone E1FF
UK Orange 0000
UK O2 10FF
UK Virgin 2800
UK Tesco 0AFF
UK T-Mobile (never close lock 2)

Once you have calculated a lock 2 code using a GID1 HEX value, enter this code in the same way as code 1 but change the end value to indicate this is lock 2:

#pw+4567267026+2#
