Xperia z3 compact locked

[OkiTuning]

Hello!

I'm writting because i realized that my Sony Xperia Z3 Compact is hardlocked due to incorrect unlock codes...

I checked that by *#*#7378423#*#* where i found this:

[x] Network 0
[ ] Network subset 0
[ ] Service provider 0
[ ] Corporate 0
[ ] SIM 0

So i'd like to know if there is a solution to unlock my phone...

Waiting for solutions

Thank you

I am from Bulgaria.

Contact your carrier or your Local support, I've read somewhere that they might be able to reset the count so you can try a different code. 

Note: sony doesn't provide this unlock codes.
