I am using HTC 7 pro mobile phone which is installed with the new windows phone 7 operating system. Now I am looking to get a SIM card which can offers me 3G service in India. I have recently heard about the new TATA DOCOMO and they recently launched 3g service. I want to know what are the tariff plans of TATA DOCOMO 3G service. Someone please help me by giving its tariff plan.
