There's been a sweeping change across the United States’ biggest wireless carriers. Over the past decade, the leaders of Verizon, T-Mobile, and AT&T oversaw a shift from simplistic feature phones into the era of smartphones and streaming.

Facebook is testing a new app to expand internet access in developing countries. The app, called Discover, provides users with a balance of free browsing data provided by several mobile partners. Facebook is running the first trial in Peru, but it plans to launch in a number of other countries in the future, including Thailand, the Philippines, and Iraq. Users will receive free data from their provider each day and will get a notification when it’s available.
