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 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.
