The New York Times ran a poignant story about the travails of children unable to go to school in Indonesia. Today, about 13 million people across 12,500 remote villages have no access to the internet, said Setyanto Hantoro, president director of Telkomsel, the country’s largest telecommunications company, which is cooperating with the government to provide service in far-flung areas. Among the areas where Telkomsel is working to bring access are Kenalan, where the three girls study by the road, and the village of Bah Pasungsang, where as many as 20 students a day climb trees to study. But those efforts will not be completed until 2022, Mr. Setyanto said.
