Try BSNL WLL or BSNL EvDO. Speed depends on your tower. When I planned to buy EvDO, I was told that not to expect speed more than 115 Kbps as my tower support only that much. I think it is unlimited for Rs. 750. BSNL WLL Tarang phone is also a good option. I think it comes unlimited for Rs. 250 including telephone (please check price at exchange). A friend of mine using it. Getting around 15 KBps. It is slow, but cheap, unlimited and good. May be you are lucky enough to get 2 Mbps speed on EvDO. Someone from local exchange can give a better idea. Hope this helps.
