I recently shifted to new place when I changed my job and thought of trying vodafone 3g data card now after a month and a half usage.
I feel that I made the wrong decision. firstly, the net is very very slow. secondly if 2 or more than devices are conncted the connectivity starts tumbling and eventually disconnects. I have earlier used airtel and was very happy with and I am thinking of weitching back to it . even the customer service is very slow.
