While Siri is undoubtedly useful and engaging, many iPhone and iPad users are unsure how to use it or cannot even locate it because it does not have a dedicated app icon. There is no need to worry, as a complete guide on using Siri on iPhone and iPad is available. Following this tutorial, you will learn how to activate Siri, use its features effectively, and enjoy the convenience it offers.

Part 1: How to Enable/Disable Siri on iPhone
In order to use Siri, the first thing you must do is to turn on the service on your iPhone or iPad. Actually, when you first set up your device, it would ask you whether you want to enable Siri or not. But you do not need to worry if you do not enable it at that time since you can go to Settings to turn it on anytime you like. Before accomplishing the setting, please make sure that your device is iPhone 4S or later. In addition, the internet you used must be stable.
- Click on "Settings" on your iPhone or iPad.
- After entering the Settings, you will see some categories, just find out "Siri" and tap on it.
- Slip the slider next to "siri" to turn it on.
And oppositely, you just need to slip the slider from right to left to disable Siri when you do not want to use it.

Part 3: How to Edit Siri Command on iPhone or iPad
It is known to all that there is nothing perfect in the world. Siri is the same. Actually, in our daily lives, even our families would misunderstand our words, let alone an intelligent service. Therefore, it is understandable that Siri would misjudge your questions or commands. And when the misjudgment happens, you need to repeat your requirements or edit your original question manually. To edit your command or question, you can:
- Activate Siri using the Side button or by saying "Hey Siri."
- After Siri responds, look for the command you just gave at the bottom of the screen.
- Tap the text of your command to open the editing screen.
- Make the necessary changes to your request.
- Tap "Done" on the keyboard, and Siri will process the updated command.

Part 4: How to Set a Passcode for Siri
You cannot set a separate passcode specifically for Siri, but you can control when Siri is allowed to work while your device is locked. This protects your information and prevents others from using Siri without permission. ([How to Reset Restrictions Passcode on iPhone/iPad?)
- Open "Settings" on your iPhone or iPad.
- Tap "Face ID & Passcode" or "Touch ID & Passcode" and enter your device passcode.
- Scroll down to the "Allow Access When Locked" section.
- Turn "Siri" on or off depending on your preference.


If you turn it off, Siri will only work after you unlock your device with your passcode, Face ID, or Touch ID.

Siri can help you with a wide range of tasks. You can even ask Siri directly what you are able to request. To get started, here are five of the most useful voice commands for Siri.
1. Check and manage your calendar
As a virtual assistant, Siri can help you keep your schedule organized. You can ask simple questions like "Do I have any meetings today?" or "How many days until my birthday?" You can also give more detailed instructions, such as "Remind me to call Mom when I leave work." Siri can create calendar events as well, for example, "Schedule a meeting with Pete next Tuesday at noon." (Top 4 Methods to Sync iPhone and iPad Calendars)
2. Open the camera
Siri cannot take photos for you, but it can open the Camera app. You can even specify which camera to use. Saying "Take a picture" opens the rear camera, while "Take a selfie" opens the front camera.
3. Search your photos
Siri can quickly find photos in your library. For example, you can say, "Search for photos I took in Spain," and Siri will show all the pictures from your trip. You can also narrow your search by date or by person. (Photos Disappeared from iPhone?)
