SOURCE: RESTRICTION CODES

hi if you tell me what county and network the phones locked to and also the imei number i can give you the unlock code but i need this info so i can use the software to generate the unlock code

SOURCE: RESTRICTION CODES

Special Code/Service Provider Lock Code:
This code is required to allow a phone locked to a particular network's SIM cards to be used with a SIM card from another network. Orange and T-mobile lock handsets in this way, though O2 and Vodafone are beginning to lock PAYG and WAP handsets. The unlock code varies from individual handset to handset.
Blacklisting:
This is not a security code, but it works like one! To help combat mobile phone thefts, the networks share a database of the IMEI (International Mobile Equipment Identity) of mobile phones that have been reported stolen. Once a phone is on this list, it will not be allowed to use any of the networks.
This can be a risk if you buy a second-hand phone, because if it has been stolen, or if an unscrupulous seller makes an insurance claim after selling, the phone you bought in good faith may be permanently disabled.
Be very careful to check the source of a second-hand phone!

Hi,

RESTRICTION CODE:

To get restriction code you have to call your previous service provider. This code is provided to prevent in case of theft taken place the other person cannot use your phone in other networks.

While you get the restriction code ,the previous service provider customer care officer will ask for your personal details to check whether the mobile belongs to you only.If they are satisfied with your answers they will provide with the restriction code.

These codes are always free.DONOT pay money for these codes.The website which provides these codes are fake.DONOT trust them.
Thank You
