I have noticed couple of points while having Airtel connection at my place which are horrible, (An honest feeling)
The broadband speed is shared by Airtel as per the number of customers in that area, You will only get good speed for few hours in a day, rest you might only regret taking the connection and paying so much.
Every now and then connection goes down and it will take minimum 24 hours to up that connection. 24 Hours that actually 2 working days they claim. Seriously?
There is no reliable service provided by Airtel customer support and the basic reason is they have shortage of manpower all across the country. In my opinion Airtel is no more going to stay as they have more competitors then ever with a big player like Jio Broadband coming soon.
My suggestion is if you are going to purchase a broadband please check other local vendors first, Even BSNL & MTNL is better than Airtel now a days with higher FUP data and a very less cost.
I am going to remove this Airtel connection from my life.
