How to unlock TATA Docomo 3G dongle ???

Recently i have unlocked TATA Docomo 3G USB stick, in this post i will be sharing you the easiest and simplest way to unlock Huawei modem.

Before going further on how to unlock modem, lets see what is this lock and unlock mechanism.

When you buy a phone or modem from telecom service providers, it will be locked to there network. i.e it will be configured to work only for particular frequency of network. If you change SIM card, frequency gets mismatch and this makes your phone not work.

Unlocking is a mechanism wherein you need write a simple unlock code to your cellphone or data card. Once you put the unlock code your mobile or modem it will start catching other networks. Most of the vendors do this once the contract gets completed, but you don't have to wait till that time, here is a simple trick, just follow them and unlock it now.

Note: In internet if you search about unlocking modems, you will get most of the softwares to generate unlock key and you can't unlock your modem with them, You need to look for modem un-locker software. DC unlocker is one among them.

1) First download DC Un-locker software here.
2) Remove SIM card from dongle and plugin to your system.
3) Select your modem manufacturer based on your modem type, here i am selecting ZTE huawei modem,
Select appropriate model.

Once you click on search button, DC unlocker scans your device and shows the status as its locked or not.
If its in locked state, right side Unlock button will get enabled.
4)Once you done everything just click on unlock button present at the right side of window, that's all. You are done, you can observe the status in log window. If it says success its unlocked and your dongle will be capable of connecting to any network.

Here how the final log looks.

Now insert different Network SIM cards like Vodafone, Airtel, Idea, Aircel, Uninor etc... it should detect automatically.
