I used BSNL for my internet usage but due to non-sense functioning and worst services I finally switched on to Airtel Broadband service after a suggestion from my friend and it is really working good. Guys! The internet service is too good from Airtel. What it has got interesting in its plan is that the internet speed will not reduce even if it is a unlimited usage plan. There are no restrictions on speed such as BSNL. It has been veru convenient for me. It has been almost six months that I am using this service from Airtel and no such day has come yet that connectivity has been lost or speed is not coming. In my point of view, it is definitely a good service by Airtel and if you are facing problem with other companies then you must switch to it.
