1. what is the total installation cost + security deposit + any hidden charge i need to pay them for getting the connection?
2. and rental needs to be paid in advance or after month completion?
3. and is this connection broadband only or do they force you to get telephone connection too,which means extra charges due to telephone fixed charges?
1.Installation cost was a Rs 600 cheque at the time of registration thru a local reliance connection provider
2.Once you get your connection you have to pay 2 months advance rental of something close to 2k if you're on the 4mbps connection, after that it's month to month.
3.You can choose to get only the broadband, I don't remember reliance forcing me to get the telephone line, but I'm thinking of getting it since I don't have a fixed line phone in my home.
Some tips - I suggest you keep a backup connection just incase from another ISP because with reliance its headache right fro the start to the point when your connection goes down, it takes days until something is even done about it.
I have a mini directory of reliance engineers and local contacts when it goes down.
The CC is completely useless, they only do something when you angrily yell at them on the 3rd day of your connection being dead. Threaten them with complaints to trai or say you wont pay the bill
Lastly you might wanna get well acquainted with all the people you have to deal with, that means you gotta pay them something to expedite the installation of your connection. I had to wait for 2 weeks to get my connection, I used to call the local engineers, Reliance CC everyday till someone finally showed up. even after all that I had to pay the engineer something to get my line installed. They are very helpful when your connection goes down since they know what's happening locally.
Bottom line - The connection works as advertised but there are some issues like slow dns servers so might wanna switch to Google's dns's from time to time. HTTP download max at about 500+ kbps, torrents can be a tad slower. Streaming sometimes is slow but mostly works great. I average about 250gb in downloads each month...with no data cap or speed reductions the 4mbps for the price is probably one of the best connections in India. Now only if reliance got their shit together.
