Soon after the unlocking of H3G Tre Italy E3131 (E3131S-2) modem, finally I got the solution for unlocking of Airtel Nigeria E3131 Huawei 4G dongle. Unlocking process of the Nigerian E3131 is also same, as it also comes with un-customized firmware, and there is bulky process involved.
How to unlock Airtel Nigeria E3131 Huawei 4G Modem?
1. Download Airtel Nigeria E3131 Huawei 4G Dongle unlocker tool from the link which is provided at the end of the post.
2. Now disconnect the internet and change the default SIM card with any another network provider SIM (other than Airtel carrier SIM card in Nigerian E3131 Huawei 4G modem).
3. Now connect the modem to Windows PC or laptop.
4. Let it launch the software of the modem.
5. Close the software of modem (Huawei Mobile Partner software of Airtel brand).
6. Run the downloaded Airtel Nigeria E3131 Huawei 4G Huawei modem unlocking app.
7. Detect the device into the downloaded software.
8. Once it will show the IMEI, input the correct 8-digit SIMLock / unlock code in “Unlock Code(6-8 digits):” box and click on OK button.
Now your Airtel E3131 modem is unlocked forever.
Note : If your device firmware version is 21.157.72.00.408, then it can not be unlocked. It comes with zero attempts left to enter the code.
Note : I provides the Huawei wifi mifi routers / gateway unlock codes also in cheap rates.
