Changeing the imei code can be charged with 5 years of jailtime.
Why don't you take it to a local service center, they might be able to restore it there.

What is imei


The IMEI (International Mobile Equipment Identity) is a unique 17 or 15 digit code used to identify an individual mobile station to a GSM or UMTS network. The IMEI number provides an important function; it uniquely identifies a specific mobile phone being used on a mobile network. The IMEI is a useful tool to prevent a stolen handset from accessing a network and being used to place calls. Mobile phone owners who have their phones stolen can contact their mobile network provider and ask them disable a phone using its IMEI number. With an IMEI number, the phone can be blocked from the network quickly and easily.

It is important to note that swapping a SIM card will not stop a phone from being banned. IMEI numbers are stored in the phones themselves, not on the SIM cards.

An IMEI is only used to identify the device and does not relate to a specific individual or organization. Other numbers such as the ESN (Electronic Serial Numbers) and MEID (Mobile Equipment Identifiers) can link an individual to a phone. Usually, an IMSI number stored on a SIM card can identify the subscriber on a network.

There are several ways in which you can locate your mobile phone's IMEI number. The IMEI can usually be found on the handset, beneath the battery, sometimes printed on a small white label. Another way to easily locate your IMEI phone is to dial the following sequence of numbers into the handset: *#06#. If you have a Sony Ericsson mobile phone, you can retrieve the IMEI by pressing the following key sequence: right,*, left, left,*, left, *, left.
The Structure of an IMEI Number

IMEI numbers either come in a 17 digit or 15 digit sequences of numbers. The IMEI format currently utilized is AA-BBBBBB-CCCCCC-D:

  • AA: These two digits are for the Reporting Body Identifier, indicating the GSMA approved group that allocated the TAC (Type Allocation Code).
  • BBBBBB: The remainder of the TAC
  • CCCCCC: Serial sequence of the Model
  • D: Luhn check digit of the entire model or 0 (This is an algorithm that validates the ID number)

G600 in trying to fix the network lock the imei are all zeros


Hi there,

First you will need to obtain the IMEI (serial number) for your handset. Type *#06# from your handset. The number that appears is the IMEI. Once you have this number you need to contact the Mobile Operator Customer Service department or use an online Subsidy Unlock service.


The phone must be in portrait mode. Once in portrait mode hit the Dial button on the touchscreen.

Type #7465625*638*Unlock Code #.
(Unlock Code is a unique 8 digit number).
Device will reply: Network Lock Deactivated.

Thank you for using FixYa! Have a nice day and please remember to rate this solution.

Warm regards,

I recommend you contact your service provider.



Blacklisted or Barred Handsets

What is it all about???
A phone may be blacklisted (or barred) for many different reasons, but the most common reason is that it has been reported either lost or stolen! It is only the networks (Orange, T-Mobile, O2, Vodafone etc) that have the facility to blacklist a handset.

If you are unfortunate enough to either lose or even worse have your phone stolen you should report it to your service provider (your network) immediately!
Your service provider can then blacklist the handset so that it can no longer be used to make or receive any calls. The networks do this by adding your phones serial number onto a national blacklist database (Central Equipment Identity Register). Effectively the handset becomes absolutely useless and the thief is in possession of a pretty paper weight! :-))


So How Does Blacklisting Work?
Every mobile phone has a unique serial number. This serial number is called the IMEI number (International Mobile Equipment Identity). It can normally be found underneath the phones battery and it is 15 digits long.

Now each time you switch your phone on or attempt to make a call the network systems check the IMEI number of the handset you are using. At this point the IMEI number of your handset is cross referenced with the Central Equipment Identity Register. If the IMEI number of your handset is on the CEIR then the network will either:

1) Refuse to send a signal to your phone (No signal strength at all)

2) OR WILL supply a signal but will not allow any outgoing or
incoming calls.

If your IMEI number is on the CEIR your handset is blacklisted and therefore useless.

Resetting Security Code


SIM pin code:
This is a pin code that locks the sim card until you enter the correct code. This protects your account, even
if your sim is put into another handset. To reset it, you need the PUK code:
Pin Unlock Code (PUK)
If you miss key (or forget) your SIM pin code, and enter the wrong one 3-5 times in a row, the SIM will lock up, and you’ll need to enter the PUK unlock code to release it. You should ask your Network Service Provider for this code when you need it. Don’t try to guess it, because after a few wrong guesses, the SIM card will be permanently disabled.
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.
Which is the one that you want?
The default security code for Nokia is 12345
