    No network

    OK. Unlocking seems to work but now I can't get any network connection with the data card. (Another DC from huawei and the same sim card works very well.)

    Is this related to the "diagnostic port"?
    The ZTE data card led isn't flashing anymore and the windows hardware manager shows only "ZTE Diagnostics Interface" (COM7) and "ZTE NMEA Device" (COM8)

    MWconn doesn't find any network signal.

    Code:
    Detecting card :

selection :
manufacturer - ZTE modems
model - Auto detect (recommended)

Found modem         : K3565-Z

    For the logbook:

    I'd tried some AT commands on the data card:
    (There's still no led visable!)

    Code:

IMEI: XXXXXXXXXXXXXXX

OK

    Have your unlocking software killed my data card?

      DC Unlocker not killing modems. By sure you using not customized connection software, SIM is working and signal from network prowider is in a range. Also dont forget input right APN parameters.

        I hope so. Perhaps the modem was broken from the beginning.
        (Hmm. But I saw a red flashing led before unlocking. Now it's off. Very confusing.)

        Did you have understood what I've written? I talked to the modem via serial console (PuTTY) via AT commands.

        The signal is perfect at my site. (Verified with another modem and a "normal" cell phone.)

        The APN is required for the setup of an data connection. The association to the cell network is independend from an data connection and works "automatically".
        (And this association is not working with the ZTE modem!)

        For comparison: Here's the AT conversation from another Huawei modem, that ist working perfectly with the same SIM card.

        ATI

            As I mentioned before it's not a software problem, since the modem can't associate/login to the cell network, which is independent from any software - it happens automatically if the SIM is unlocked by PIN (if anyone is set).
            But exactly this subroutine/hardware module doesn't work.
            In my opinion no other (dialing) software will help, except from a flashing (re-)program tool or something like that.

            In fact that you can't or want not help me, it seems the best if I gave the modem back to the shop.

            If I get a new one from the shop, can I unlock it with the credits from the "broken" one or have I pay another time for unlocking?

              Yes, you would need to buy again. Unlock can not cause this.
              We think that your modem should be unlocked.

                Yes, your software and the modem itself claims that it's unlocked.
                But this doesn't help me, since the modem is not really working.

                Thanks a lot for your useless replies.

                  Good news: I've got the modem working.

                  For all the other users out there - It seems to be neccessary to install the "Vodafone Mobile Connect Lite" after the unlock process.
                  During setup of Vodafone Mobile Connect Lite the modem will be initialized (and the led flashes first "red", then "green") and could now be used with all other tools / operating systems.

                  Now, the AT results change after PIN verification:

                  @The administrators: I can't believe to be the first one with this problem.
                  So why are you kidding me with such stupid things, like APN parameters?
