There’s a new feature of the iPhone iOS 18 update that you need to know about. Satellite messaging is a feature that allows users to text family, friends and emergency services when they don't have cell service. For instance, maybe you’re in the wifi-less forest and want to let someone know you’ve gotten to your campsite safely. To connect to a satellite, you need to be outside with a clear view of the sky and horizon. Then you’ll point your iPhone upward. It’s free for the first two years and is available on iPhone 14 or later.
