Steps

Using Wi-Fi or Cellular Connection

  1. Put-a-SIM-Card-Into-an-iPhone, if necessary. Depending on how your got your iPhone and your service, you may need to insert a new SIM card into your iPhone before activating. If you bought a new iPhone directly from a carrier, it will usually come with the SIM card already inserted.
    • The SIM card must be activated by your iPhone's carrier. If you're attempting to use a SIM card from a carrier other than your own on a Check-if-Your-iPhone-Is-Unlocked phone, you won't be able to activate your phone.
    • If you bought your iPhone in a carrier's store, they probably already inserted and activated the SIM for you.
  2. Power on your iPhone. You'll do so by holding down your iPhone's Lock button until the white, Apple logo appears on the screen.
  3. Begin setting up your iPhone. Doing so entails pressing the Home button and selecting a language and region.
  4. Tap a connection option. You can connect to a Wi-Fi network to which you have the password or you can tap Use Cellular Connection to activate your iPhone over data.
    • If you choose to connect to Wi-Fi, you'll be prompted to enter the network password.
    • Using data to activate may result in extra charges on your bill.
    • If you only see Connect to iTunes here, you'll need to connect your iPhone to iTunes on a computer to activate through iTunes.
  5. Wait for your iPhone to activate. As soon as an Internet connection is established, your phone will attempt to activate itself. You shouldn't have to wait for more than a few minutes before the activation is complete.
    • You may be required to enter your Apple ID email address and password before the activation will begin.[1]
  6. Proceed to finish Set-Up-an-iPhone-from-Scratch. Doing so will entail choosing a backup from which to restore your iPhone (or setting it up as a new iPhone), entering your Apple ID, and setting various other preferences. Once you reach the Lock screen, your phone has successfully been activated and set up.

Using iTunes

  1. Make sure iTunes is running the most recent version. To do so, click the Help tab in the upper-left corner, click Check for Updates, and then wait for iTunes to look for an update. You'll click Download iTunes if prompted.
    • You'll have to restart your computer after updating iTunes for the changes to take effect.
    • You should also sign into your Apple ID with iTunes if you aren't already signed in. To do so, click Account in the upper-left corner of the screen, then click Sign in and enter your Apple ID email address and password.
  2. Turn on your iPhone and begin setting it up. You'll be prompted to select a language and region.
  3. Tap Connect to iTunes. This will be displayed beneath any available wireless networks.
  4. Connect your iPhone to your computer with the charger cable. The USB (larger) end plugs into a port on your computer, while the smaller end of the cable goes into your iPhone's charging port.
    • If iTunes isn't already open, it may start automatically depending on your iTunes sync settings. Otherwise, you'll need to open it.
  5. Click Set up as new iPhone or Restore from this backup. Choose whichever method is suitable for you--neither will adversely affect the activation process.
  6. Click Get Started when prompted, then click Sync. Doing so will synchronize your iPhone with your iTunes library, thereby activating your iPhone.
    • You must have an internet connection for this process to work.
  7. Proceed to finish Set-Up-an-iPhone-from-Scratch. Doing so will entail entering your Apple ID, creating a passcode, and setting various other preferences. Once you reach the Lock screen, your phone has successfully been activated and set up.

Troubleshooting

  1. Contact the owner of a used iPhone. If you've purchased your device secondhand, you may be greeted with an Apple ID login screen before your device is able to activate. This is the Activation Lock, and is designed to prevent thieves from activating stolen iPhones. If you encounter this, you'll need the previous owner to remove the iPhone from their account or have them sign in on the iPhone. There is no other way around this.[2]
    • If you can contact the previous owner, have them sign into icloud.com/settings with their Apple ID and remove the iPhone from their "My Devices" section. This will allow you to activate the iPhone as your own.
  2. Restart your iPhone if you see an "Invalid SIM" message. Doing so may get rid of the problem, though there are a few other things that may be causing this error:[3]
    • Try toggling Airplane Mode on and then off again.
    • Make sure your phone's operating system is up-to-date.
    • Try removing and resetting your SIM card.
    • Ensure that your iPhone is unlocked if you're using a SIM card from a carrier different than the one you got your iPhone for. For example, if you have an iPhone that you got from AT&T and you're trying to use a Verizon SIM card, you'll need AT&T to unlock your iPhone first.
  3. Restore your phone to a previous backup with iTunes. If you can't activate your iPhone no matter what you try, you may be able to fix the problem by restoring it:
    • Connect the iPhone to your computer and open iTunes.
    • Select your iPhone at the top of the window and then click "Restore iPhone."
    • Wait while your iPhone restores, then start the setup process and attempt to activate it. The restore process may take a little while to complete.
  4. Contact your carrier. If your iPhone won't activate after restoring it, your carrier will probably have the answer to your problem; in fact, they may be able to activate it for you over the phone or in the store.

Tips

  • It may take a few minutes or even hours for your number to activate on your iPhone.

Warnings

  • Activating your service and transferring an old number will typically remove any old voicemails. Make sure you have any important messages written down before activating your new service.
