I am new to mobile internet since all my life I have only used a desktop with a fixed line connection. I am now purchasing a laptop and in addition to a fixed line connection which will probably be my primary connection, I would also like to have a mobile internet connection for when I travel.
I will be based mostly in Calcutta.
There are many providers offering several plans with quite complicated tariff structures which are making me run in circles. But more than that I am at a loss to understand all the technology that is now available. I am seeing words like EVDO, 2 G, 3 G, GPRS etc and I don't really understand what they are or what is good.
I am also unable to find any one link on the internet that gives comprehensive information on what all these terms mean. Essentially I am at a loss to properly understand what is going on.
Can someone please initiate me on this? I will be very grateful if someone can refer me to some links where I can read about the current status of mobile internet in India and understand it so that I might be able to make an informed decision on what technology/provider/plan I should go far.
If not, if someone can offer me some useful pointers, I will much appreciate.
