Tired of memorizing new PIN codes? We show you how to change your SIM card's various PIN and PUK codes in less than 5 seconds.
Although most people remember their primary SIM PIN code, those othercodes - used for various verification purposes - are never to be foundwhen needed. Below we've included a set of short codes which, whenentered on a handset's standby screen, will let you easily change PINand PUK (short for Pin Unlock Code) codes - but keep in mind, they maynot work with all handsets and mobile operators.
More importantly, when changing ones PUK codesthere'll be no help to get from the mobile operator if the new codesare forgotten, so make sure to write any changes down alongside the oldPUK codes. Also, please note that the codes should be entered withoutthe spaces shown below.
Change SIM Card PIN
** 04 * old PIN * new PIN * new PIN #
Change SIM Card PIN 2 (Write down the new code)
** 042 * old PIN * new PIN * new PIN #
Change SIM Card PUK (Write down the new code)
** 05 * old PUK * new PUK * new PUK #
Change SIM Card PUK 2 (Write down the new code)
** 052 * old PUK * new PUK * new PUK #

The phone Freeze problem. Your phone has gotten hard-locked; it will not accept any unlock codes. This problem can only be caused by improper unlocking. Basically this happens if you or someone else has already entered 5 wrong unlock codes on your phone.
You can get the unfreeze code, NCK code and SPCK code from third party. After unfreeze your phone, you have to enter the NCK code to unlock and use it with any gsm network in the world. i will suggest the website Unlock-Zone.com which is doing good service .....you can approach this website
