Having experienced the services of various operators for broadband service, I can safely say till date my best experience has been with Airtel. I work from home and hence connectivity and speed is absolutely critical. I have till date not experienced any downtime or speed issues which is really commendable.
I also am offered complimentary unlimited landline calls. The plan opted is for Rs 1049 per month with 30 GB data at a speed of 2 mbps and unlimited local calls.
