Hi friends. I want to share my experience with Reliance data card. Earlier I was using 1x from reliance with speed of around 150 kbps, but as they launched Broadband+ I also upgraded my datacard to HSD. I have taken Broadband+ 5GB day, 10 GB night Nationwide plan where additional usage charges are also 50paisa/mb, is very convenient one for me.
I am getting speed >1.4 mbps( download) & 1.0 mbps(upload) speed. I feel this is the sufficient speed while I want to run my videos, Online Games & Video Conferencing while I am in meeting.
I dont have any first hand experience with Tata & Vodafone so cant say about those. But as In my home town Nagpur, One of my friend shared his feedback that Tatas are lacking in their coverage & all time connectivity as he would have had used it earlier.
Anyways, I prefer Reliance Netconnect broadband+ as I am happy with the Tariff rates as well as Speed since I have taken the data card. while billing also, I am getting my bills on time correctly. So, as if today its the best choice for me.
