I’ve previously written a post on how to unlock huawei modems, but we were meant to understand that the process does not work for the recent Huawei modems the Network service providers make available for sales.

how to unlock huawei modems for free

Although there are ways to unlock the stubborn Huawei modems such as the E303 series, but it usually requires using the services of unlock softwares such as DC unlocker which of course is not a free option.

In this guide, I’ll teach you how you can unlock any huawei modem without paying a dime such as the DC unlocker option for unlock credits. Follow the steps carefully to successfully unlock your Huawei modem as this has been working for me.

Steps To Unlocking All Stubborn Huawei Modems Without Paying For Unlock Credits

1. Click Here to visit the website where you would generate the unlock code.

2. When the page loads, click on the Google plus icon to log in with your Google plus account (You must have a functional G+ account to use this service). If you are using the calculator First time it will ask you to Accept Terms and Condition click on “I Accept” and proceed.

3. Once you log in, type in your Modem’s IMEI number and Model series in the appropriate form boxes provided and click on “Calculate“.

4. The Unlock code would be generate but won’t be visible till you click on the +1 button to share the page. Sharing the page on G+ using the button reveals the Unlock code to unlock your huawei modem.

5. The code generate would look like this

Model No. :     E303s-1
IMEI :     834548010418202
NEW ALGO CODE : 88028383
OLD ALGO CODE : 35410271
FLASH CODE :     94602058

Copy the codes generated to notepad. The problem you face is knowing the particular code you are to unlock the modem with. But don’t worry, Click Here and insert your modem’s IMEI number then click on “Submit IMEI“.

This would help you determine which of the codes would unlock your modem.

If it loads a result as “Please Proceed To Huawei New Algorithm!” then the NEW ALGO CODE generated by the unlocker is your modem’s unlock code, else if you get “Please Proceed To Huawei Old Algorithm!“, then the OLD ALGO CODE generated is what you need to unlock your Huawei modem.

6. Now insert an alien sim (SIM not supported on your huawei modem) into the modem and plug to your computer, you will receive a dialogue box pop up asking for your modem’s unlock PIN, input the NEW or OLD ALGO CODE generate as your case may be and click on the UNLOCK button provided.

Hurray! You just unlocked your Huawei modem without paying a dime. Please do not be stingy 🙂 . Share this article with your friends on Facebook, Twitter, Google Plus, Linked In, and your email list just as a sign to say thank you. I would really appreciate.
