  1. Entering the code in DC-Unlocker tool doesn’t do anything. I have asked this same question on several forum and no one seems to be replying. I hope this forum won’t be the same. After entering the AT^…. code in DC-Unlocker tool, what do you do next? Is the command effected just as soon as you enter it or you have to do something like pressing some buttons on your system. Some said you should press the enter button but that hasn’t helped either. Because doing that only takes the cursor to the next line waiting for me to type. Thanks

  2. I’ve tried all I can “both processes” to unlock my Airtel E173 modem, since the unlock code is 0… Any remedy??

    • This guide only applies to older versions of modems. I will update us with a method to reset unlock code counuter to Zero for latest modems like yours.

      Thanks for visiting Kevin.
