How to check account usage of BSNL from non-BSNL network. Its for my relative, who is using the 500 plan and he wants to check the usage of his account from office, as suspects there have been increased usage of his account when he was at office and there is no one else who is using it at his home for sure. He wants to check the usage while at his office which has airtel. He could not login to his bsnl account checking login there. Is there any tweaks or tricks to access it through a different ISP than BSNL?
