Some Huawei modems after flashing also it does not ask for the unlock code. Like you may have already faced earlier problem about Airtel Huawei E173CS-1 latest firmware. We have already given the solution for this modem, but in this post we want to highlight some topics. Recently when I was unlocking some Airtel Modem, a few modems was asking for unlock code while putting another SIM on the modem but some of them was not asking for unlock code. If you have also stuck after getting the unlock code, what you will do? Huawei modems are asking for unlock code then its will get unlocked after the providing the unlock but what you will do if your modem is not asking for the unlock code.
