I had subscribed to Airtel USB modem - Data Card. there i was given 1GB/month for Rs 599. i was assured a speed of around 240Kb/s. i hardly get speed of 100kb/s. after i got my bill, i was shocked to see.the bill was huge. this is because, ther is a minimum usage of 1MB every time i login/connect.meaning that even if i connect, but don't use, it will be considered 1MB, and if i use more than 1 mb, the count will be considered rounded...
