My phone is locked and i need it unlocked new phone never used it.. it only takes 4 codes..

Most new Sony will ask for the unlock code when you put a sim in it wont yet accept because it is locked.

Your unlock code is :
CCK: 260704XXXXXXXXXX
NCK: 221877XXXXXXXXXX
NSCK: 40710XXXXXXXXXX
SPCK: 34120XXXXXXXXXX

The letters CCK, NCK, NSCK, SPCK indicate which code to use the different locks on your handset.

So you need to find out which lock is active on the handset ( But usually you'll only need the one marked NCK).

To do this you need to look in a secret menu on the phone

Tap the following in as if you were dialing a number to make phone a call...

*#*#7378423#*#*
A new hidden menu will appear.
Tap on service info
Tap on SIM lock

If you have [x] Network 5 - this means your phone needs the net NCK Code
If you have [x] Service provider 5 - this means your phone needs the SPCK Code

Other Models: 97% Sony Ericsson

1 - Switch ON your phone without SIM Card,
2 - Press 1 time the left arrow,
3 - Press 2 times the button * ,
4 - Press 1 time the left arrow,
5 - The message 'Personalize with MNC2' will appear,
6 - You can now enter the Unlock Code we send to you.

If your phone have a 'JogDial' (ex : Sony Ericsson K700i) you must press 'Down Arrow' instead of 'Left Arrow' for step 2 & 3. We mean by 'Down Arrow' to direct the JogDial down !

W950 models need to use * up * down ** down (up/down using the jog dial on the side).

If you still have the card where the SIM-card was embedded that was delivered in the package when you bought the phone: on that card is the PUK code, that is what you need to give in when asked.

Unlock Code is a manual hard-lock on handsets which requires the correct pass code to allow access to the phone's functions.
Occasionally, people purchase used handsets. Previous owners may have locked the handset and are unreachable to get the new pass code

To unlock the phone using the factory default pass code, perform the following:

1. Confirm the phone shows, Enter Unlock Code.
2. Press the MENU button. The screen will show, Enter Security. Try both.
3. Enter last 4 of PTN, unless you have changed the lock code, and press OK. OR
Enter six zero's (000000) and press OK.
*If successful, the screen will display, Phone Unlocked.
*If unsuccessful, the screen will display "Security code is incorrect please try again."

If the you don't know the code, You will need to contact Motorola to have it re-flashed, which may incur a service charge from Motorola.
4. You now has access to use the phone’s functions.
5. Do not change the Unlock Code.

Use this service, it's very fast and trust, tested by me.

PLEASE READ FULL INSTRUCTIONS BEFORE DOING ANYTHING

TRY WITH NO SIM CARD IN THE PHONE

Doing this is at your own risk!


Every code unlocks a certain lock. Code number 7 usually unlocks them all but some phones are 'buggy' and will not accept code 7 at first then use code 1.

Usually you only have to use code 1 or code 7.

#pw+xxxxxxxxxxxxxxx+1#

1. Press ( # ) on your phone
2. To get ( p ) press ( * ) 3 times within 1sec
3. To get ( w ) press ( * ) 4 times within 1sec
4. To get ( + ) press ( * ) 2 times within1sec
5. Enter the 15 digit code
6. To get ( + ) press ( * ) 2 times within 1sec
7. Enter code number
8. Press ( # ) on your phone

Now your phone is unlocked!

If your phone isn?t unlocked after code 1 or code 7 then you have either entered the wrong IMEI or Network. Sometimes there could also be a problem with newer software versions. Then you can try another 'Boxserial' Remember! You have only five tries to enter the right code. After that you will need a cable to unlock your phone. So please, be aware

Let me know if you have any problem follow these instructions and you should be ok.

I think it needs to be done with no sim card in the phone remember you only get 5 goes after this if its still not unlocked then the only other option is with a lead and unlocking software.

This should solve your problem let me know how you get on ok

This is done at your own risk!
