On Monday, Apple introduced iOS 18.5, extending emergency satellite capabilities to iPhone 13 users for the first time, whereas previously, these features were exclusive to iPhone 14 and later models.

The iPhone’s emergency satellite system is intended for critical situations where cellular or Wi-Fi signals are unavailable, allowing users to contact emergency services, send satellite texts, share information with emergency contacts, or request roadside assistance.

The primary focus of the iOS 18.5 update is to provide access to carrier satellite services, such as those offered by T-Mobile in partnership with Starlink. Users can check for this feature in the Cellular menu within their iPhone’s Settings.

Thus far, this feature has been credited with saving lives, according to rescuers, including assisting lost and injured hikers, rescuing people from wildfires, and more.

Although the expansion of satellite emergency services to iPhone 13 owners is the most significant addition in iOS 18.5, iPhone users will also receive several smaller updates.

One of these updates includes a new feature for Screen Time, Apple’s parental control software, which notifies parents when their child correctly enters the parent’s passcode to access Screen Time permissions.

Other improvements include an updated Mail app with easier access to the “All Mail” category as its own tab, a new Pride wallpaper, and a more straightforward way to subscribe to content from the Apple TV app on a smart TV or connected device. Additionally, Apple has resolved a bug that caused the Apple Vision Pro app to launch with a black screen when downloaded from the App Store, along with other bugs affecting Siri, enterprise apps, and more.

The release of iOS 18.5 was accompanied by iPadOS 18.5, which primarily addresses bug fixes, as well as visionOS 2.5, watchOS 11.5, and security-focused updates for macOS Ventura 13.7.6 (22H625) and macOS Sonoma 14.7.6.
