Reliance GSM data plans

• The default plan charges Rs 10 per MB upto 50MB and Rs 1 per MB after the 50MB limit. 
• The other plan is Rs 99 for 2.5GB per month. 

Basically reliance sells bandwidth at following rates:

• Rs  10.00  per MB 
• Rs    1.00  per MB 
• Rs    0.04  per MB 

The default plan costs 250 times the cheapest plan. That is best use of behavioral economics I have ever seen.
