Root [International] Unlock Bootloader = Unlock Network?

[Rexkh]

This is a question. If I unlock my bootloader, is that mean, my network is unlocked too?

No, one has nothing to do with the other. One is in the bootloader, the other is in the modem. The only thing they have in common is the word "unlock".

So, to unlock network without code, do I have to root the device? Example of model LG Optimus G E973.
