Hi airtel offers unlimited 128 kbps GPRS connetion @Rs.300/PM. I want to know how the speed is when using it on PC. My friend at Delhi used airtel 128 kbps broadband @Rs. 700/PM.If one can get same speed and unlimited connection with GPRS, why should one opt for the later plan.What is the truth behind this? What are the shortcomings of GPRS connection.
