Remember, you should always take the whole costs into account - Registration Charges, Activation charges, Usage and Download Charges.
Best of luck for your puchase and business.
Tata and reliance - the speed is good but it is very costly and  if you can try  bsnl i can say it is the best.
Bsnl - unlimited can cost you around 775 with takes it  comes to 850 for 256 kbps.  Airtel can cost you 900.  But  In tata  u can have prepaid  ,  say your usage is just around 2 gb for 6 months then it just cost you around 2500 for 6 months for 512 kbps.  If u have hathway in your area try it , it is the best and cheapest. ,
bsnl for sure
