Airtel always launches the devices with customized firmware, means if you will change the SIM and connect to PC, you will not get any option to enter a unlock / NCK code. Previously I had also unlocked Airtel 4G E3272s-927 Huawei modem of India, and I had shared it for free. But, this time, the situation is different, it comes with firmware version 21.470.05.02.284 and Airtel Bharati has changed the security of the data-card and people are facing the problem. For those who wish to unlock his new Airtel 4G E3272s-927 Huawei modem can refer this post. However, this time, the solution is paid, not free.

    • Use internet download manager to download the file, still problem then download from other PC or download in mobile. Problem with your PC not with my file.

      For mobile connector, extract the file using WinRAR software. You have assigned ISO file to open as burning software, thats’s the reason it is opening with Image Burning software.
