Newer Sony Models (Xperia Range)
Most new Sony will ask for the unlock code when you put a sim in it
wont yet accept because it is locked.
When you receive your unlock code(s) they will look similar to the example below:
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
