Summary
Hi Brian, Thanks a lot for a wonderful add-on. It is a real time saver. There seem to be some complaints by people about BSNL data usage not showing. It really isn?t a problem with the add-on. It is in-fact, the problem with the data on the BSNL site not being updated real-time. Keep up the good work!

Developer’s Description

By Brian Fernandes

Use bandwidth monitoring tool for BSNL's DataOne service.

If you use BSNL broadband in India, you no longer need to visit the site to check your bandwidth use, just use DataFox instead. DataFox will get the details from BSNL and display them inside chrome for you. If you enter your bandwidth limit, DataFox will also display a handy pie chart indicating whether you are using your bandwidth at an acceptable rate - or not.
