Now, the rate of new mobile internet subscriber growth is slowing. From 2015 to 2021, the survey consistently found over 200 million coming online through mobile devices around the world each year. But in the last two years, that number has dropped to 160 million. Rest of World analysis of that data found that a number of developing countries are plateauing in the number of mobile internet subscribers. That suggests that in countries like Pakistan, Bangladesh, Nigeria, and Mexico, the easiest populations to get online have already logged on, and getting the rest of the population on mobile internet will continue to be a challenge. GSMA collects data by surveying a nationally representative sample of people in each country, and then it correlates the results with similar studies.

Max Cuvellier Giacomelli, the head of the Mobile for Development program at GSMA, said that large swaths of the world’s population still don’t have access to mobile internet primarily because of affordability. Although the cost of data has dropped radically in recent years, the International Telecommunication Union, a UN agency focused on information and communications technologies, notes that huge disparities between regions persist. The cost of data in Africa, for example, is more than twice that of the Americas, the second most expensive region.
