Huawei Logo 151x151Unlocking a Huawei E173 U-1 HSDPA Modem USB Stick, branded as Tchibo Internet-Stick, and enabling its voice functions is illustrated by using the software DC-Unlocker and updating to a firmware comprising voice functions on Windows 8.1. Finally, this modified Huawei E173 U-1 HSDPA modem USB stick is utilizable as a GSM Gateway on FRITZ!Box models which are capable for mobile broadband modem USB sticks, e.g. on a FRITZ!Box 7390.

I conducted the modification with the following set up:

The work around on Windows systems is as follows :

  1. Download and install the Huawei ‘Mobile Partner for Windows‘ software (version dated 12/05/2012).

  2. Insert the SIM-card, connect the Huawei E173 U-1 to your Windows PC and wait until it is installed completely. Do not install the Mobile Partner software provided with the E173.
  3. Download and install the latest DC-Unlocker software
  4. Start DC-Unlocker, select manufacturer ‘Huawei‘, select model ‘Auto detect (recommended)‘ and then click on the magnifier icon to run the DC-Unlocker detection: The detection results is that voice feature is ‘disabled‘ and that the SIM lock status is ‘Locked (Card Lock)‘.
  5. Close Mobile Partner and DC-Unlocker.
  6. Download firmware update 11.126.85.00.209.B427, extract the ZIP file and install it as administrator.
  7. Restart DC-Unlocker, select manufacturer ‘Huawei‘, select model ‘Auto detect (recommended)‘ and then click on the magnifier icon to run the DC-Unlocker detection: Now the detection results is that voice feature is ‘enabled‘ and that the SIM lock status is still ‘Locked (Card Lock)‘.

  8. If you need to unlock the E173, buy credits (Prices). For unlocking this E173 I needed 4 credits (=4 EURO), paid per PayPal. Click on ‘Server‘ and login with your ‘user name‘ you created during buying credits and with the password which was sent to your email address after purchasing credits.

  • Insert the unsupported SIM card in your modem and plug in to your computer.
  • Follow all the installation procedures until to the last prompt to ‘Input the unlock code‘.
  • For Huawei models get the unlock code from Huawei unlock code calculator or from Online Huawei Modem Unlock Code Calculator. You will be provided with two codes – the unlock code and the flash code.
  • Now copy the unlock code, paste it in where you are prompted to Input unlock code and press ‘OK‘.
  • Install DC Unlocker Client (Windows only) and check the unlock status.

Now your Huawei E173 U-1 is unlocked and voice functions are enabled!

Unlocking  Huawei E173 U-1 modem USB stick and enabling voice functions is simply done by using DC-Unlocker for SIM unlocking (costs are 4 EURO), or by the cost-free alternative option, and DC-Files for updating the firmware including voice functions (for free). This updated E173 U-1 USB modem can be used as a USM modem GSM Gateway on FRITZ!Box models like a FRITZ!Box 7390.

Stay tuned! 😉

    This is a good one but many modems like the one I have have customized firmware thereby resulting in firmware update failed when upgrading the firmware. The only method that works on customized firmeware is temporary unlock which usualy relocks on unplugging and halting. By the way you can use a free software called huawei modem unlocker to unlock free of cost in contrast to the dc unlocker which is costly.

    Hi Gee,

    I’m about to test the installation on my 7390 as well. Any updates on UMTS sticks available, as those mentioned might not be available any more.

    Cheers
    Eckhard
