Unlocking the Huawei E1550

My wireless broadband connection is majorly flaking lately and I’ve been considering switching to another provider. But what to do with my Huawei E1550 USB modem which is SIM-locked to my current provider? Why, unlock it, of course!

The following are the steps I took to unlock my modem. This might not work for YOU. I’m not responsible if you brick your modem. Bricking your modem is always a risk. Butsince I’m planning to switch providers anyway, I figured had nothing to lose.

First, you need to get an unlock code. The easiest way is to go to this site:

http://www.bb5.at/huawei.php?imei=<your IMEI here>

If the unlock code doesn’t work, you will need to download an alternative calculator:

If that still doesn’t work, just google “Huawei E1150 unlock code” and, with some diligence, you’ll find plenty of unlock code calculators.

Once you get the code, you need to send it over to the modem with this tool:

Run it, detect the modem, select the COM port, unlock, enter your calculated unlock code, and press enter. That’s it! Your modem should now be unlocked.

  2. Hi,

    After you ‘Run it, detect the modem, select the COM port and then click unlock ‘ this above mentioned codewriter just sits there. It does not show one any option whatsoever to enter the calculated ‘unlock / flash ‘ codes.

    So what exactly are you talking about ?

  3. @sam – try increasing the resolution of your screen as the dialog box for entering the unlock code seems to appear in weird places.

  4. I found it all right thanks to Jay. I used the Huawei E1550 Code Generator and the Huawei E1550 Code Writer and still it did not unlock at all. Now I have exhausted all the chances to unlock this 3G modem.

    Ohh well ! !

  6. Hi Anyone,

    These are the details of my present Huawei USB Data Adapter. I used the Unlockers and Codewriters on the internet to unlock it.
    But these efforts did not work.
    So what else should I do ?

    Can someone let me know the right unlock code ?

    DEVICE NAME : E1550
    IMEI : 351911040852629
    Serial No : B55TAA1030131827
    HARDWARE VERSION : CD6ATCPU
    FIRMWARE VERSION : 11.608.14.00.356

  9. I have a Huawei E1550 Idea Netsetter USB Modem. So I took the following actions to unlock it. This could work for you. I dont guarantee it though.

    You need :

    a) Huawei Unlocker.

    b) Huawei Modem Code writer.

    c)Huawei_firmware_E1550_StarHub_Update_11.608.13.02.00.B418.

    You can also download the dc-unlocker_client-1.00.0528. This will allow you to find out whether your E1550 is SIM Unlocked when you are done executing all the above steps.

    You should download the firmware and the other Software mentioned above.

    Run the Huawei Unlocker so that it produces the ‘Unlock Code’ and the ‘Flash Code ‘. You need the Flash Code. Copy Paste both this data somewhere.

    Run the Firmware Software. It will ask for the ‘ Flash Code ‘ This will overwrite the existing Firmware within the E1550.

    Now you could remove the SIM card that was installed in the Data Modem.

    Now you should run the Code-writer and input the 8 digit Unlock code. Now you simply hit ‘unlock the Modem’ button. If you don’t see any error in the first instance itself , I think you should be OK.

    This is it your done. It will not display anything else( it did not produce any message that the modem is unlocked or not). It will simple sit there. Now you can test your modem by trying other SIM cards in it.

    Please do remember that you have to select your AP and Profile names accordingly.

  23. @Elder,

    I do not think that this is a problem. You can try the following. Save your :-

    a) Huawei Unlocker.

    b) Huawei Modem Code writer.

    c)Huawei Firmware

    On to a USB / Jump /Flash Drive

    Now uninstall all instances of Huawei Software from your PC.
    You can try downloading a later/ better versions of the above mentioned Software. You can now try the above mentioned steps all over again. Good Luck ! ! !

    You will have to search around a lot. You will need to google.
