    Followed the instructios given here and effortlessly unlocked two Huawei mobile broadband dongles. Both now connect through my USB Router to service my home wireless network. The unlocking software is provided to unlock a Huawei K3520 modem, it also worked for my K3765 modem. Provided that a valid unlock code is generated by the software and the modem is recognised by your computer’s connection management program, it does exactly what it says on the tin!

    Hi, this procedure seems to have worked. I got the OK message.
    But, could you tell me how I can check that the modem is unlocked ? I know this is silly but I would like to be sure!

      Put another network sim and you will get the signal means it is unlocked. Or you can check in dc unlocker log status of your modem.
