ZTE USB modems and MiFi routers can be unlocked easily if it asks for unlock code after changing the SIM card (other than default). But, a few devices, like Airtel MF90, Idea MF90 Plus, and some others do not ask for NCK code after changing the SIM card. It is very difficult to determine that unlocking attempts are left to enter or not.

This post will help you in checking the unlock code counter. You can only try up to 5 wrong attempts in ZTE modems and routers. Once 5 attempts are finished, there is no way to unlock the device.

How long we need to wait for an unlock code of ZTE?

The approximate delivery time for an unlock code of ZTE starts from 1 hr to 24 hrs.

The average response time is 2 hrs (Based on last 100 orders).

How to Check Unlock Code Counter in ZTE USB Modem and Hotspot Router?

1. Download DC Unlocker.

4. Click “Search” Magnifying glass.

5. It will detect the device and display the details of connected router/modem.

Note: In my case, I am trying to detect the unlock code counter of ZTE 305ZT WiFi router.

6. At the end of the result, in a new line, paste the following command:


7. Now, press Enter from the keyboard.

8. Now, it will return +ZNCK: 5.

Here, number 5 is unlocking attempts left to enter the code into the device. If you will try to unlock with wrong codes, then attempts will keep decreasing. Once the remaining attempt will be 0, then you can not unlock the device.
