Unlocked BL, Custom ROMs and Sim locked phones - XPERIA X10 Q&A, Help & Troubleshooting

Hi,
I am using a 3 network locked phone. now since I already have an Unlocked bootloader and will flash stock rom with either wolfbreaks or Oodies, will it network unlock my phone?
similarly if I get an unlock code from 3, and unlock my stock gingerbread rom, will I have to buy another sim unlock code every time I change my rom?
Thanks

no.
sim unlock is permanent.
you dont have to unlock it again

What happens to the provider lock when I upgrade the rom?

I have unlocked my xda 2 and it is working fine.... what happens when I upgrade my ROM with the official 02 rom as and when it is available.... will it relock itself to the network and if so will it be just as easy to unlock it again (and will the unlock number be the same).
Many thanks

The unlock will remain unlocked.
yup once unlocked always unlocked

No, SIM unlock is independent of the ROM. dont worry, flash another rom.

You're confused with bootloader unlock and sim unlock. Sim-unlock allows you to use any network-provider on your phone, Bootloader-unlock allows you to install a custom kernel to your phone.
If you want to unlock the bootloader to flash a custom kernel, your network may be lost, because your phone wasn't sim-unlocked using an imei code, but it's not that your sim-lock is activated again.
You can get your network back by flashing back to stock Sony Ericsson kernel and then restoring your bootloader using S1Tool.

[Q] If i SIM unlock my phone, will bootloader unlock allowed=Yes ?

I bought my Z2 from EE in the uk and i was very sad to find out that EE and other carriers stop you from unlocking the bootloader. So if i sim unlock my phone from EE, will i be able to unlock the bootloader? If not is there any other way i can make it say yes??

No and no.
This has been answered before. If you bootloader is locked, there is no practical way to unlock it.

Rooted & unlocked question

I'm selling my Sprint Note 3 that I had rooted before the lollipop upgrade. Since then I put a lollipop rom on it.
Two stupid noobie questions that I couldn't find answers to when I searched ..
1. Since I'm rooted am I also unlocked ... can he use an att Sim card and use it on att?
2. Do I need a specific rom that would make this possible ... or is there a way to test it to prove to him that it works?
Thanks for the answers.
Just FYI... There's a difference between unlocked carrier and unlocked boot loader.
You do not need a custom ROM to use another Sim card, but you need to unlock the carrier on the phone
Sent from my Nexus 9 using XDA Free mobile app
Is there a way to tell if I did a carrier unlock? I don't really even remember what method I used to root it.
You unlock the boot loader to flash a custom rom?
To sim unlock you would have had to run SSU.app or GT.app to international unlock then odined a older radio mj4 or mi3. Then change the APNs to match the carrier's settings for internet and mms messages.
I called sprint and got the master unlock codes ... is there an easy way to unlock it now that I have those?

Unlock SIM with Custom Stock Rom Possible ?

Hello,
I wanna Sim-unlock my phone (galaxy s5) but it's running on cyanogenmod. I know it's not possible to unlock sim with a custom rom but is it possible to unlock the phone if I flash a Stock Rom? And does the rom have to be with original branding?
Greets,
Kenny
EDIT:
No, it's not possible to unlock your phone on a custom firmware. Yes, you have to flash the original firmware with branding by the phone's original carrier then unlock it for all networks. This will work. You can use a custom firmware again after unlocking the phone.
