How to Turn on 5G on iPhone with iOS 17

Before we get into the nitty-gritty, let’s understand what we’re trying to achieve here. By following the steps below, you’ll enable 5G on your iPhone, which means faster and more reliable internet connectivity, provided you’re in an area with 5G coverage. Let’s get started.

Step 1: Open the Settings App

Tap on the Settings app on your iPhone’s home screen.

The Settings app is the gateway to all the configurations and customizations you can do on your iPhone. It’s the one with the gear icon, and it’s usually on the home screen.

Step 2: Tap on Cellular

Scroll down and tap on the option labeled ‘Cellular.’

Cellular settings are where you manage everything related to your phone’s connection to the mobile network, including data usage and network selection.

Step 3: Tap on Cellular Data Options

In the Cellular menu, tap on ‘Cellular Data Options.’

This menu is where you can toggle data settings, including enabling LTE and, in this case, 5G.

Step 4: Tap on Voice & Data

Inside the Cellular Data Options, tap on ‘Voice & Data.’

This is where you can switch between different types of network technologies that your phone can use for calls and data.

Step 5: Select 5G On or 5G Auto

You’ll see a list of options. Tap on ‘5G On’ to always use 5G when available, or ‘5G Auto’ to let the iPhone decide when to use 5G to optimize for battery life.

Selecting ‘5G On’ ensures that your phone always uses a 5G network if it’s available. ‘5G Auto’ is more battery-friendly and will switch between 4G and 5G based on how you’re using your phone.

Once you complete these steps, your iPhone will connect to a 5G network whenever one is available. You’ll notice the 5G icon on the top right corner of your screen, indicating that you’re on a 5G network.
