How to Unlock Usb 3g datacards (Aircel + Airtel + Bsnl + Vodafone + idea)

I sucessfully unlocked my Aircel Huawei E1750 today(19.10.2011). I expect You can unlock any Huawei Modem in this method.

But I am not tested all types, just give a try at you own risk. In first try I unlocked My datacard.

1. Find the unlock code using the IMEI no of your datacard from the below software link given in Method : 2.

2. Now remove the aircel sim and insert some other sim (Airtel or BSNL) in your data card.

3. Now connect the datacard to pc.

4. It will show a window asking unlockcode enter the code.

5. Now you can use any sim in your data card.
