A study by Portio Research says that the worldwide mobile industry appears to be resilient to the financial turmoil that many other industries are experiencing. The top growth markets for wireless are China and India (not surprising), which will contribute more than 1 billion additional subscribers between 2007 and 2013. Brazil is a distant third with 132 million additional subscribers expected by 2013.
However, the study did note that mobile voice and data revenues continue to decline with mobile ARPU expected to fall from $23.2 in 2005 to $15.8 by the end 2013, largely because the additional subscriber growth will come from low per capita income markets.
