Asia has 51% of All Mobile Subs, Pacific Basin Up to 66%
If we can speak meaningfully of a region spanning the Pacific Ocean, and therefore including Asia and the Americas, then that "region" includes 66 percent--two thirds--of global mobile subscribers.
That is significant for several reasons, including the fact that global fixed voice lines now number only about 800 million. In other words, there are 7.8 billion carrier voice lines in service, of which mobile represents about 90 percent of all lines.
So knowing the volume of mobile lines very nearly captures the extent of voice line usage in any region, the trend being most pronounced in “developing” regions.
Asia alone represents 51 percent of global mobile subscribers.
