after a hell of a search, i found this great tool to unlock my idea net setter usb stick. in normal condition the modem works only with an idea sim card in it. but after its unlocked, you are free to use it with any sim card which has gprs activated. i myself use an aircel sim in the idea net setter i have. this tool can unlock any huawei device which is great b’coz many other products like photon, reliance net connect and mts blaze use only an huawei modem device.
