Unlock your Sony Xperia Z4 SOV31 phone permanently and safely with the factory SIM unlock code available from sim-unlock.blog. No need to change the firmware or risk voiding your phone's warranty. Unlocking by code is the fastest and most secure method, and recommended by the manufacturer. Once unlocked, you can use your phone with any GSM network around the world.
Getting started is easy. Simply provide us with the 15-digit IMEI of your phone, which you can find by dialing *#06# on your device. We'll use this IMEI to generate the correct unlock code from the manufacturer's database. The average waiting time for an unlock code is 1-5 days.
Please note that new T-Mobile and MetroPCS phones are locked to the "Unlock App" and cannot be unlocked by code. In such cases, you will need to place an order for the "Device Unlock App."
If you have a Sony phone, please check that the phone prompts for an unlock code, and that there are remaining attempts to enter the code before placing an order for a Sony unlock code. We have provided a detailed procedure for checking remaining unlocking attempts on Sony phones on our website.
If you have any questions, please don't hesitate to contact us before placing your order.
