NCK code sony k510i when i update software it screen shows incorrect sim card i contacted sony service they told insert NCK code from where i know nck code (network unlock code)

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).

Satio

Enter # p w + CODE + 1 # into your phone.
Tap repeatedly the star key to get p w + symbols

The NCK number or code is provided by the Service Provider (SP)

I was not able to get a free NCK code for the mobile model that you have specified.You can get the NCK code for your Sony Ericsson W580i from Theunlockarena.com by specifying the country and network to which the mobile is locked to.You will receive the unlock code along with free unlock instructions.

NCK code and Network unlock code are same..Your SONY ERICSSON K608I locked to network...You need to Unlock it from Current network lock to use with other GSM Network sim card...Visit the site

You can get the NCK code through online..........give your IMEI number and get the unlock code for ur mobile.... i will suggest the website Unlock-Zone.com which is doing good service .....you can approach this website.
This site is nearly perfect and they were recommended highly in the cell phone forums. I used them to unlock my cell phone. contacted them and within 30 mins i had my unlock code and my phone was unlocked.
Hope this helps.

It seems your mobile is just an patch unlock so every time you update your phone it will lock to its original provider, but if the erom and gdfd_sw_bin if flash,it will permanently unlock and you can use any sim provider no matter how many update you make. This method is so technical and it will be fixed by using gsm gadget instead,most mobile service center have this tool. instead of asking for a paid unlock code which is more expensive, unlocking service by going to any the neatest mobile service center is more cheater and it is negotiable instead than online unlocking service.


Good Luck...
