One more thing I got from DC-Unlocker that it is designed with new ICERA Chipset not with Qualcomm. I insert TATA Docomo SIM card and modem easily detected it without any unlocking process. But Vodafone default software not permission to connect any other SIM card than Vodafone. Currently I have no direct solution to access this modem using other SIM card but we can use this modem without any software using Windows Dial-up feature.
