By 2012 operators will be making $67bn of revenues through SMS?

As per a new report from Portio Research - by 2012 global SMS revenues are expected to reach US$67 billion, driven by 3.7 trillion messages. Though
the growth of SMS revenues will not be as aggressive as the growth of SMS volumes due to declining prices,

SMS continues to be a phenomenal success as the cheapest, quickest and easiest to use form of peer-to-peer mobile communication. Markets have continued to grow and greatly exceeded the predictions of similar research carried out in 2005.

By 2011, the report predicts, mobile instant messaging (MIM), especially in markets such as North America, will supplant SMS as the mainstream messaging service as smartphones and wireless Internet proliferate.
Operators, the report suggests, need to strike a balance between SMS and IM pricing in order to prevent the cannibalisation of SMS revenues in the future.
