How to Unlock Sony Xperia Z Ultra?

1 – Switch ON your phone with a Non accepted SIM Card,
2 – Phone will ask you to enter Sim unlock pin
3 – Enter unlock code (16 digit code)
4 – Phone will be unlocked

Warning: Before place an order you need to check Counter Lock Status:

Power on with not accepted SIM Card
When it asks for NCK code, enter the first code
If it says Wrong code, then Open the Dialer and enter the following sequence: *#*#7378423#*#*

2. A menu will appear.
3. Go to: SERVICE INFO
4. Go to: SIMLOCK
5. Check wher is X
6. If X is on NETWORK and value is different than 0, you can unlock the phone with our codes.

in case if the phone shows (X) network lower then 5 and not 0 , then it wil be refunded

in case if the phone shows (X) network - 5 means the code was not even seen by phone, cause the counter was to be lowered to 4 at least in case of wrong code

and most important, this is for bricked and security damaged phones

some phone just show like this

() network 5
() service provider 5
() subset 5
().... 5

for such screen counter was not checked properly or the phone is bricked by software (5 locks on)

it must show

(X) network
(5) service provider
(5) subset
(5)....

    Worked in minutes was really fascinated by the process
  • Jhon Bravo on 07/22/2025
    Juro que esto pensaba que no era real. Compré un 15 PM y me salió muy barato No Blacklisted por T-Mobile com contrato y aún en garantía tiene 6 meses de uso. Está gente lo desbloqueo y me quedo full el teléfono con todas las sim y me costó muy poco, el desbloqueo si es algo costoso comparado con la competencia pero es increíblemente efectivo.

    I was a little skeptical about the website; this is my first time using this type of service. Everything was very fast, about 3 to 4 hours to unlock my iPhone carrier restriction. Thank you so much!
