Okay so let me start , I applied for Beam Telecom seeing its economical plans accompanied with higher bandwidth and also I have heard that they have recently improved a lot after upgrading their core infrastructure..
So I was like why not give it a try as I have already tried out various other ISPs (Reliance, Airtel). I got my connection only after some one week I applied for it. I had to repeatedly call them to get my connection. The excuse from their side was they had to increase the hub ports at my building premise as all of them were already occupied. So finally after one week I got my connection.
The area in-charge of Beam Telecom is also personally in touch with me to get the status on the connection. Apart from that they also seem to have upgraded the number of customer service lines so you don’t need to wait so long for getting your call to be answered. So overall, all seems to be well now with Beam Telecom. Hope it continues.
