I used it in Sweden. No problem.
All of us with unlocked bootloaders have used it as it's the only way to unlock the bootloader
the way they tell you to unlock i didnt do but either way you need to go there to get your unlock code
i used flashtool, not adb oem unlock
It works in India too, I got my Unlocking code, Now I can flash Custom Roms without any error

[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.

Have anyone tried to flash a unlocked firmware and get "OEM Unlocking" for N950U?

Hi, just want to know is there any possible to get the bl unlocked for all US versions... As far as I know, there is no way to do that for S8/S8+, but how about Not 8?
Sim unlock and bootloader unlock are not the same.Unlocked firmware 950U1 is just sim unlocked, you will not get an unlocked bootloader. And sim unlocked firmware will not unlock your sim on 950U model as far as I know.

Hello everyone, I hope someone has an idea if I can unlock the bootloader or its impossible, because I've been trying more than a month to find a way to unlock my bootloader to root the phone but not a single chance and my phone is Canadian was locked to bell but I unlocked the phone.
Thanks
