iOS 17: How to Turn On Cellular/Mobile Data on iPhone

posted on May 7, 2025

Turning on cellular data on your iPhone is crucial if you want to stay connected on the go. Without it, you might miss important emails, updates, or the chance to share that perfect photo on social media. In just a few simple steps, you can ensure your iPhone keeps you connected whenever you’re away from Wi-Fi.

Step by Step Tutorial: How to Turn On Cellular Data on iPhone

Before diving into the steps, it’s important to know that turning on cellular data will allow your iPhone to access the internet even when you’re not connected to a Wi-Fi network. This is perfect for those times when you’re out and about, but remember, it might use up your data allowance depending on your mobile plan.

Step 1: Open Settings

Open the Settings app on your iPhone. This app looks like a gear and is usually found on your home screen.

In the Settings app, you’ll find a plethora of options to customize your iPhone experience. Think of it as the command center for your device.

Step 2: Tap Cellular

Scroll down and tap on the Cellular option. In some regions, this might be labeled as Mobile Data instead.

This section of the Settings app controls all the cellular data options, including turning data on or off for specific apps.

Step 3: Toggle Cellular Data

Find the Cellular Data switch at the top of the screen and toggle it to the on position. It should turn green.

Once this switch is turned on, your iPhone will be able to connect to the internet using your mobile network.

After you complete these steps, your iPhone will start using cellular data to keep you connected when there’s no Wi-Fi. This means you can continue to browse the web, check emails, and use apps that require an internet connection.
