Apple iPhone 8 and 8 Plus Setup & User Guide


This guide gets your iPhone 8 or 8 Plus set up and working the way you want it. We take you through inserting the SIM, setting up email accounts, connecting to Wi-Fi and everything else you need to know to get a slick and secure iPhone. 

If you've had an iPhone before and want to restore a backup, here's our guide to restoring from an iCloud backup. Or, if you're switching from an Android phone, take a look at our guide to switching from Android to iPhone. Follow the steps or just skip to the chapter you need in the contents.


1. User manual


Apple iPhone 8 and 8 Plus user manual

If you're looking for Apple's official user manual for the iPhone 8, you'll find it here:


2. Box contents


Here's what you'll find in the box:

  • iPhone 8 or 8 Plus
  • Wired EarPods
  • Mains power adaptor
  • Lightning to USB cable
  • Lightning to 3.5mm jack adaptor
  • Information pack with SIM tool attached


3. Inserting your SIM card


You'll need to insert a SIM card into a new iPhone 8 or 8 Plus before you turn it on. The iPhone takes a Nano-SIM, which should've been given to you when you got it. If you don't have one though, your mobile network provider will be able to send one to you.

The SIM card fits onto a tray that pops out of the right-hand side of the phone.

To remove it, slide the long end of the SIM tool into the pin-hole and push it until the tray pops out. 

Drop the SIM card onto the tray (there’s only one way it fits) then slide it back into the phone until it clicks in.


Take the SIM removal tool out of the information pack (it's a metal clip that you'll find stuck to a piece of card).


Push the tool's pin into the hole on the right-hand edge of the phone, below the Power button.


Press the pin against the spring that's inside, and when the tray pops out, pull it out of the phone.


Put the SIM card into the tray with the metal contacts facing down, then slide the tray back into the phone until it's all the way in.

4. Completing Apple's Setup Wizard


Now you've installed the SIM card, you're ready to start setting it up. Press the Power button on the right-hand edge of the phone for a second or two - until the screen lights up.

When the phone comes on, you'll see the first screen of the 'Setup Wizard' - a series of steps that helps get the iPhone ready to use.  Don't worry if you find any of it confusing, we explain each step, along with some super-helpful pictures.

Press the Home button (below the screen).


Pick the language to use on your iPhone.


Choose the Country or Region you're in.


If you've got an iPad or iPhone running iOS 11 already, bring it close to the new phone to set it up automatically. If not, tap Set Up Manually.

Pick your home's Wi-Fi network from the list. You can use your mobile connection to get the phone set up, but it'll be downloading a lot of data, and that could get expensive. 


Type the Wi-Fi password and tap Join.


When you see a tick beside the network name, the phone's connected. Tap Next.


Touch ID is Apple's fingerprint recognition, which can be used to unlock your phone and make purchases (as well as other things). You can set it up now if you like, but we'll cover it in detail further down, so for now tap Set Up Touch ID Later.

If you're skipping past Touch ID, you'll need to confirm by tapping Don't Use (you can still set it up in the future if you want to). 


Create a passcode to protect your phone. Type your passcode, and when you're asked, type it in again.


The standard Passcode is a 6-digit code of numbers. Tap Passcode options to change it to any of the following:

  • Custom Alphanumeric Code: a password that's got letters and numbers in
  • Custom Numeric Code: a password that's just numbers 
  • 4-Digit Numeric Code: a normal PIN number

To set your iPhone up as a new phone, tap Set Up as New Phone. If you want to move your data and information from an Android phone, or restore from a backup of an old iPhone through iCloud or iTunes, then tap that option and click the link at the top of the page to see our guide.

If you've already got an Apple ID, type the ID and password into the phone and tap Next.


If you sign in, you'll be asked about using 'Two-factor authentication'. If you've used any Apple kit in the past, you'll get a code to activate your phone. If not, tap Continue to set it up, or tap Other Options to skip.

That's the Setup Wizard finished. Tap Get Started to start using your new iPhone.

5. Connecting to the internet


You probably connected to your home Wi-Fi when you were doing the Setup Wizard, but you'll probably need to connect to other Wi-Fi networks too. These steps show you how.

Connecting to a Wi-Fi network

Tap the Settings icon.

Tap the network that you want to join.


Type the password and tap Join.

A blue tick will appear next to the name of the network when it connects. The status bar at the very top of the screen shows a Wi-Fi icon when the iPhone's connected. When it's not, the mobile network type is shown instead. 

Turning mobile data on or off

Whenever you phone isn't online using Wi-Fi, it connects to the internet using your service provider's mobile network.

If you don't want to go over your allowance, you can turn mobile data off using these next steps.

After the account is set up, you'll see it in the Accounts list on the phone.

If your email account doesn't set up automatically, you might have to put the settings in yourself. We've written a detailed guide to email server settings to help you get it done.
