Airtel India had launched a 4G dongle, which is known as Huawei E3272s-927, which is a sub-model of E3272. It is available in two firmware versions: 21.470.05.02.284 and 21.436.33.00.284. Both firmware version devices can be unlocked easily but by a firmware change method. When you try a traditional method to unlock the Airtel E3272 dongle, which means changing the SIM card and connect to the PC, it will not prompt you to enter the unlock code. It comes with customized firmware, and there is 0 attempt left to enter the unlock code. Since there are no attempts to enter the code, you cannot unlock it by code.
Now, after the traditional method, the firmware change method comes. When you replace the original firmware with un-customized firmware, then you can unlock any modem/router by code. But, you should always note that all firmware is not suitable for every dongle. If you run untested firmware, your modem may be bricked, and you will lose your dongle.
Our team has tested both the firmware with un-customized firmware and got success in unlocking. This means now you can unlock it without any fear.
