I recently shared the unlocking procedure of customized Airtel’s Huawei E5573s-606 mobile WiFi router of India. Leading carrier of Nigeria, the Spectranet is also selling the same model router in the country, which also comes with zero (0) attempts left for unlocking, which means the router comes with customized firmware. However, finally, I find the solution through a firmware upgrade, and the device was successfully unlocked.

  4. I unlocked mine since about 3 years ago, and it has been working fine up until 2 days ago, it just stopped working with the network signal light showing red.

    I’ve tried resetting the mifi modem, changed to different network SIM cards and even inserted the original Spectranet sim into the modem but nothing seems to be working as the red light is permanently on.

    Don’t know what could have caused this as is was working perfectly before the red (signal) light suddenly came on.
