Samsung GT-C5510 is locked..need this unlocked to access New Zealand network...

If it is an unlocked phone then it will be unlocked to all networks, you can swap to other GSM networks.Some phones come network locked.Therefore if a user needs to change the phone should be unlocked either through the network provider or third party unlockers like Simpleunlocking.com where they offer permanent unlock solution for many mobile models.

Hello mate, You can get samsung sgh unlock code and LG KF390 unlock code from telstra provider but you must pay some charges and wait for a couple of weeks for that unlock code. Another shortcut you can purchase reliable samsung unlock code at third parties sites on internet.

you can contact the service provider...........

Pullout your battery and look closer at the back.. should be there in plain text. That's on the phone not on the battery.

the phone card you are using may not be compatable with the new zealand telstra. from personal expeirence in australia (lived in brisbane for three months) if you have or the other bloke has owned the phone over a year they will give you the unlock code. the other possibility is that you have accepted and installed an update over the wireless service. that will lock your phone again
