Amar, you guys would be Lucky if you would be able to use 6GB Data on 2G, and that even from BSNL.
In my town, bsnl 2G/3G is for those who have little less important things in their life and need to spend most of the
time with phone settings, calling/visiting customer care, ask friends about some stupid trick among friend circle.
they are not affected if they are offline for few days a week, but still they have handsets to play as much settings and locate
data signals from their rooftop.
For other serious users, there's "Chalne Wala 2G and 3G " (workable 2G & 3G) available where you spend some money but don't have to pull your hairs, or bang you cellphone on the wall in frustration or visit/call c.care every day
So I would still not fall for such offers 😛issed-off:
