Simple, In Flat Rate plans assume you are opting for 1999 Flat Rate plan Just divide it by 10 That means you are allowed to use 200Gb and you can still download further there would be no problem.
There will be no problem if you download 600Gb.. Just make sure your average of three months is 200Gb or whatever applicable soft fair usage on that plan.
In todays Broadband Scenario where other broadband providers like Airtel are charging Rs 200-300/Gb and Reducing the Speeds. This Hayai Broadband is providing you the same speed throughout the month. But their sole condition is Be fair to them and they will be Fair to us. Actually their whole concept is to provide High speeds at Rs 10/Gb ( pretty cheap compared to other Isp who are looting by caharging 100,200,300 Per GB and Reducing speeds to 256/512kbps.
and part from that they're offering upto 1Gbit/s(If your ethernet card supports) plan that is known as "
pay as you Go" That means you have to Pay 550 Every month and you can buy your Required Gb's in Blocks from 1 to 1000Gb where each Gb would cost you Rs 10. So if you are low end user and look out for High speeds
You would have to pay
550+450(45 Gb)= 1000 Bucks.
- 1 Gb means 1 Gb upload and 1 Gb download and not like our Airtel who mixes both of them
- They are also offering wireless services from 8mbit which would initially cost you 299 and you would get 30Gb
- They have Got Dc++ sort of thing Called Hayai Zone where you can transfer files at 1gbit speeds within Hayai India network at no Extra cost.
I just found out now... Would take this plan next month
