Need network key for unlocking my handphone

Every cellphone uses a preferred network which is normally locked into the phone's own electronics, not in the SIM card. To get the network unlocking code you need to ask for it from the network service provider (Vodafone, Orange, O2, etc.) who supplied the phone, not the SIM card. After the unlocking code has been entered you should be able to use the phone with any valid SIM supplied by any network service provider. So you would be free to choose a service tariff which best suits your phone usage from another network service provider in your country. Some market stalls and shops offer a phone unlocking service for a fee but using these may invalidate the service agreement for the phone and may not allow you to choose and use a SIM for any other network from then on. Also be warned that if you also buy a new SIM from such places you may find that your phone is not actually unlocked but it is now locked to another network. Also the cellphone charges that will be applied for calls made on whatever network the new SIM uses may be much higher than what you could get if you were free to choose a SIM and service tariff, which best suits your phone usage, from another network service provider.
In other words, be very careful about what you are buying! The answers below were given by earlier by other people. Answer type in 00000000 and that is the default password. (8 x 0'S) Answer I have tried the zeros and it does not work at all. It will probably be 8 digits, and as far as I have seen you have to call the service provider in order to unlock it. Answer The *#9998*3323# Method:


1. If you have changed your phone password, change your password back to the default 8 zeros (00000000).
2. Put a SIM card that is from a network other than the one your phone is locked to
3*. When Incorrect SIM error comes up, type *#9998*3323#.
4. White screen will appear with an exit option. Press the right softkey.
5. From the menu that appears, select the Malloc Fail option. This will reboot the phone and the normal service screens will appear.
6*. Type *0141# and then press the green call key. "Personalization" or "Personalized" will appear.
7. Turn off your phone and put the original SIM back in.
8. Turn on your phone. You will receive a prompt to enter a password.
9. Type 8 zeros (00000000)
10. Completed.


* Note for steps 3 and 6, it may be necessary to enter the code several times
