What is Unlocking?
Mobile phone networks add a sim lock to their phones so that they can prevent you from using their handsets with alternative network sim cards. Most people prefer to choose which network they want to use with their phone, so if you legally own the phone then you should be able to choose, the networks themselves will unlock your phone for you however they usually have their own charges for this anything from £20-£35 depending on the network.

How does unlocking work?
There are several different methods of unlocking, the networks can do it for you, you can take the handset to a reputable mobile phone outlet or you can do it yourself. For mass unlocking the best method is using professional unlocking equipment which is available from our site (see Cables > DCT4) however for personal usage we offer a completely FREE no catches online unlocking facility, where you can unlock your phone yourself just by entering a few details about your mobile phone into our Nokia Code Calculator.

How to use the calculator?
Our FREE calculator will generate unlock codes for your mobile phone, the generated codes are completely unique and depend on your phones identification number, mobile network and phone type. Once all the details have been entered into the calculator several codes are generated for the different locks on the phone. The locks which require unlocking depend on your country and network, for DCT4 phones the calculator will recommend two unlocking codes, these shall be displayed in bold you should try one of these if that does not work then try the alternative. Please input the codes into the handset carefully if the codes recommended do not work please do not re-enter them incorrectly too many times as you only have 5 attempts before the phone can no longer be unlocked using an unlocking code and may only be unlocked using professional unlocking equipment which has to be connected to the phone. For further details on using the calculator please see below.

Entering the codes
