There's a chip in your smartphone that lets you listen to FM radio, but turning it on is bad for corporate profits.
Your smartphone can actually pick up FM radio. Most US phones don't have the chip turned on, but in Mexico 80 percent of smartphone users can get FM radio, which public-safety wonks love because it's a reliable way to reach populations in an emergency.
Ajit Pai, Trump's FCC chief, wants more companies to turn the chip on, but says he won't force Apple or any other provider to do so. (They keep it off in hopes you'll pay for Spotify or Apple Music.)
