For what is worth, I also got, from. my local carrier a brand new Nexus 5X. LG H790. Well, it turns out to be Network locked as well. Whenever the phone is turned on with the SIM in of another carrier it asks for: "SIM Network Unlock PIN"



I went on and bought online from two different companies sim unlock codes, from the first company: SimUnlock dot com was not able to found a code and after a few days, said so snd proceed to reimburse me.The second company: MasterUnlock dot com did return, very quickly (fte minutes after online purchase) a few codes, named

NCK NSCK SPCK CPCK SIMCK, tried the NCK and the SPCK as per the instructions received but none worked "unlock unsucessful", seems they are also reimbursing me.



So, I dont know whats next, as the carrier wont give out the unlock codes.



My Nexus 5X is locked to Mexico's carrier Telcel.
