Unlock Huawei E303 Modem Using the Huawei Code Calculator

The codes we are talking about are the ones you will need to unlock the modem. For this method, they can be generated either online, offline or free ones can be found online. Calculating the codes will rely on the Huawei Code Calculator. Here we go!

  1. First of all, find the IMEI number of your modem by checking for it under the cap of the modem. If you don’t find it here, insert your modem into a computer’s USB port and wait for it to launch the interface. Click on the Tools section then run the diagnostics. Under the diagnostics check under the Device section for the IMEI number.
  2. The second stage is determining the type of unlock code for your specific type of modem. To do that, you will need to go to Huawei Algo Check website then insert your IMEI number in the dialog box. Hit on Submit IMEI. You will be shown whether your modem uses the old or new algo calculator.
  3. When the result comes up, you will have a link to go to the algo calculator you want. However, if you cannot access the calculator from that panel, here is how to do it.


The Old Algorithm

This one can be added at this link. Once you visit the link, you will be presented with a little dialog box to enter your IMEI number. After that, hit on the Calculate button. You will then be presented with an unlock code and a flash code as well. That simply, you have the unlock code for your modem.

The New Algorithm

The new one is also free but quite complex to follow. But, thanks to us, you are a few steps away from unlocking the modem. It uses the Google Plus platform to give you the code you need.

  • Go to this link, where you will find a dialog box requiring your Google Plus email and password. Don’t worry as they won’t store your details.
  • Enter the email and password and click on the Sign In dialog box.
