Network Unlock or NCK code for ZTE Phone, Router, Gateway, Tablet
From here you can order unlock code for all ZTE IMEI (phone, modem, router) of any country and any network.
Before placing the order, change the SIM card and check; it should prompt NCK / Unlock Code / SIM Network Unlock PIN, and attempts should be left to enter the code. If you don’t know how to check the unlocking attempts, refer to unlocking instructions.
Please, don’t order an unlock code for the latest ZTE phones, which comes from T-Mobile, AT&T USA, and MetroPCS, if it has “Device Unlock App” installed. You need to order a “Device Unlock App.”
