Bsnl nic card
Network Coverage is very limited

Dear Sir,

I have the BSNL NIC Card with unlimited usage for Rs.250 per month Service Tax. The speed is 144kbps. I use it in Baroda, Gujarat. However, if I go out of Baroda to Gandhinagar or Ahmedabad or outside Gujarat, I get the message "No Network". The purpose of a datacard is the ablity to use internet on the move. This basic facility is not available on this service. I want to know whether there is a problem with my card or this service is limited to the local limit of my city Baroda only.
