If you are a subscriber to a major U.S. carrier, it might not surprise you to find out that U.S. data plans are among the most expensive in the world; that is based on the raw numbers. The average mobile data plan with 500 MB of data is $85 monthly in the states compared to $24.10 in China and $8.80 in the U.K using dollar purchasing power parity (PPP)... Using PPP, which eliminates the affects of a too strong or too weak dollar, a monthly data plan that costs $85 in the states runs only $10 in India, Indonesia, Germany, Italy, and the U.K. The cheapest spot in the world to pick up 500MB of data according to the ITU, is Austria where $4.70 a month gets you what $85 a month buys you in the states.Source: http://www.phonearena.com/news/U.S.-data-plans-among-the-most-expensive-and-most-affordable-at-the-same-time_id48063
