Locked SIM ! Help needed from experts

[Power_Getter]

I have bought Galaxy note 7 from UK, but when i tried my sim card I got a message says: Enter unlock sim code so I think the phone locked to O2 UK, Is there any possible way to hack or unlock the phone without getting back to O2 UK?
because the phone right now in UAE
I appreciate any help to solve this issue, I have no problem to pay to get unlocked. Even tried some websites with no luck

Assuming that it is a SM-N930F model you can install custom recovery / root / custom rom if you like, for example this one:

I'm sure any carrier lock is gone after doing this.

But make sure before you start this procedure, to activate developer options, and in developer options menu activate usb debugging and OEM unlock.
