Less than half, is the answer, and it will be that way for at least 2-3 more years. In November 2013, Ericsson, the venerable Swedish maker of the infrastructure that supports cell phone networks, released a report suggesting we won’t exceed 3.5 billion smartphone subscriptions until 2016. The total number of mobile subscriptions, however, will exceed 7 billion by 2014, according to the International Telecommunications Union.

Meanwhile, the total number of mobile phone numbers will also be growing, and will exceed the number of people on earth thanks to countries like India, where many people have more than one phone to take advantage of price variations in different places.
