Exclamation [Q] Impossible to debrand (Unlock) my Z1?

Hello!

I have a Sony Xperia Z1 C9603
Currently running
757 by [NUT] ( I followed this guide he have in Z1 General section )

I'm currently locked to the carrier "3 (Three)" and i wish to have it SIM-Unlocked so i can use my other SIM-Card i have,
Is this possible?

Because no matter what FTF i choose the phone is still branded and when i start the phone it keep asking me for "PIN-Code To Unlock Network"
So right now i don't have any connection at all on the phone.

Could someone please help me?

Sim lock has nothing to do with which firmware you are running.

You must either speak to your network provider or pay someone in a mobile phone shop to get it sim free

Unlocking the bootloader should allow sim unlock

The only way is to pay for a code, either from your carrier or 3rd party site. Any O2 contract owners can do it for free though.

Might be on the Z1, but I've unlocked boot loaders on a lot of HTC's and that has resulted In a sim unlock

Not on Sonys, which I've owned a few of. You need a code.
