Step 1- You need to find your modem IMEI number which is usually printed on modem or check the modem manual for your unique IMEI number for example mine IMEI number is
IMEI: :356165035539027

Step 2- Go to the link**************
Replace ************** with your unique IMEI number so that the link should be like my example below -

Open your customized link in your web browser and you will get something like this


IMEI: 356165035539027

Entsperren / Unlock: 53916665
Flashen / Flash: 36421160

(c) SERGEY/MKL 2010

Here 53916665 is your unlocking code .

Step 3- Download Huawei Modem Unlocker ( from here).Download contains a rar file you will need a compression tool like winrar to open and view files (download winrar free ).Run file name HUAWEI MODEM Code Writer.exe

Step 4- Huawei Modem Unlocker  will open (see image below)

Click on Detect button and then select your modem name from the list.after selection from the list click on Accept button.

Step 5- Finally,Click on Unlock Button and enter your 8 digit unlock code which you obtained earlier from Step2.

Click OK and done.

If you have followed all steps,then your modem will get unlocked for sure.
Well,this trick has worked best for all above mentioned Huawei modems,but if somehow this does not work for you,just post your comment and i will try to reach to you ASAP.

2. Unlock Huawei Modem Online
If you do not want to download any software and still want to unlock your modem,then YES there is an online application which can generate unlock code and flash code which is exclusive for your IMEI and works like charm for various Huawei models.

Models supported -

E1550, E155, E156, E156G, E160, E160G, E161, E166, E169, E169G, E170, E172, E176, E180, E182E, E196, E226, E270, E271, E272, E510, E612, E618, E620, E630, E630+, E660, E660A, E800, E870, E880, EG162, EG162G, EG602, EG602G
Go to this (website), enter your IMEI number,fill Capcha and click on "calculator" button.
It will automatically generates you unlock code and flash code.

Where to use this unlock code ?

To make use of the unlock code, insert an unauthorized sim card to your Huawei modem.
Unauthorized sim card means sim card from other card operators other than the one the modem is currently locked to.
When you will insert, you would be prompted for the modem’s unlock code.
You need to enter enter the unlock code which you have generated earlier form that website.
Its done now,and your Huawei is unlocked. You can now use your Huawei USB modem with sim cards from any other operator. I have tested it on my Huawei E220 and it worked.

Thanks and Cheers !!
