Most people hate Fair Usage Policies, that's because Fair Usage Policies are not FAIR enough.
Operators sell their plans as unlimited, only to restrict after a certain usage.There are thousands of debates on FUP on data services is required or not! But certainly it helps operators to keep their networks free from congestion and over-use/misuse.
We all saw how BSNL's 3G data services choked following some users downloaded more than 500GB/month.So FUP has to be implemented, but it should not hurt customers/end users.
But there are some plans with 1-10GB usage cap at high speed and then speed is restricted to such a lower level you will be disgusted.Interestingly most operators sell them as UNLIMITED plans.
These plans must be sold as FLAT RATE Plans and there must be complete transparency regarding billing details.The broadband service providers, specially Airtel and recently BSNL also are offering such crappy plans.
8GB at 8Mbit/sec and then speed will be restricted to 256kbit/sec. It simply sucks for most of the users who are on high speed of 8Mbps.Operators must come up with data top up on wired broadband - Rs 100/GB is best value for money which is BSNL is offering as 10p/MB post free usage on limited broadband plans. I personally think there must not be any FUP on unlimited 256kbps and 512kbps plans. On 1Mbps unlimited plan FUP would be 50GB, 2Mbps plan can offer FUP of 100GB. For high downloaders, night unlimited plans are best, I guess. BSNL's home broadband plans 500C and 500C+ are best sellers all over the country! Even operators can increse bandwidth during night hours, when traffic is less.
