Telecom retail revenue in Latin America will grow at a compound annual growth rate (CAGR) of 3.3 percent between 2012 and 2017, according to Analysys Mason.

Even in the United Kingdom and Germany, the markets with the brightest future, STL Partners forecasts a respective 19 percent and 20 percent revenue decline in mobile core services (voice, messaging and data) revenues by 2020.
