In iOS 14 and earlier, Siri on iPhone and iPad doesn't work properly without an internet connection. For years now, the virtual assistant has had to "phone home" and ping Apple's servers to respond to almost every request or command, which has made it virtually useless when your device is offline.

In iOS 15, however, Apple has made some major changes to the way ‌Siri‌ works. Now, all ‌Siri‌ speech processing and personalization occurs locally on your device, making the virtual assistant more secure and faster at processing requests. This also means ‌‌Siri‌‌ can now handle a range of requests entirely on-device, without needing the internet.

Once you're using iOS 15, you don't need to enable anything for ‌Siri‌ to work offline, because it works automatically. The types of requests that it can handle without phoning home to Apple's servers include the following:

• Create and disable timers and alarms.
• Launch apps.
• Control Apple Music and Podcasts audio playback.
• Control system settings including accessibility features, volume, Low Power mode, Airplane mode, and so on.

If you don't have a cellular data or Wi-Fi connection and you ask ‌Siri‌ to do anything that requires internet access – such as messaging someone, weather updates, or playing streamed content – you'll get the response like "To do that, you'll need to be online" or "I can help with that when you're connected to the internet."
