2. Insert your SIM card correctly or use a different one

iPhone SIM card

Remove the SIM card from the SIM card tray then put it back again. Make sure it fits properly on the tray and the tray closes completely. If you still get the error message, then try using a different SIM card. Probably an old SIM card that worked with the iPhone before you restored it.

You may have to contact your SIM carrier to be sure the problem is not on their end. After all, they’re better-placed to diagnose deep-rooted issues with their SIM card system. For instance, they’ll let you know if the iPhone is not compatible with their SIM card.

3. Check the Apple system status page

Go to Apple’s systems status page and check the color of the “iOS Device Activation” light. If it’s green then you should be able to activate your iPhone because the service is available.

However, if the light is yellow or red, then the Activation service is temporarily unavailable. So, you’ll have to wait for it to turn green before you try again.

4. Check your network connection

You must connect to a network to activate your iPhone. Whether you’re using a cellular or Wi-Fi network, make sure it’s working. You can change between the two in case one is not strong enough.

For example, if both of them are ON, switch the Wi-Fi off then try to activate using a cellular network and vice-versa.

Also, you can restart your Wi-Fi router, turn OFF the VPN that’s configured to the router, and connect to a different Wi-Fi network that is not public.

5. Check the activation lock

If you’re asked to enter a password during the activation process, the activation lock is enabled in Find My iPhone. This is a feature that’s used to protect your iPhone from being used by somebody else in case it gets lost or stolen. Once you enter the Apple ID and Password you should be good to go.

Now, if you got the iPhone from somebody and you don’t have their Apple ID and Password, you can ask them to log into the Find My iPhone app and remove the iPhone from their iCloud.

6. Activate using iTunes or Finder

For this fix, you must have the latest version of iTunes or MacOS, and the computer should be connected to stable internet. If you have macOS Catalina use Finder while those with macOS Mojave or earlier and PCs should use iTunes.

  • Next, launch iTunes or Finder on your computer.
  • Turn OFF your iPhone and connect it to the computer using an original lighting cable.
  • Switch On the iPhone.
  • The computer will detect your device immediately and prompt you to start the Activation process.
  • You could also locate your iPhone from the left-hand pane on the screen select the “Activate” option.
  • Log in using your Apple ID to complete the activation process.

If iPhone, still, won’t activate after restore, move to the next step.

7. Update using recovery mode

The next fix for your iPhone’s activation error is to update through recovery mode. Follow this guide:

  • First, your iTunes and MacOS should be up to date.
  • Launch iTunes then connect your device.
  • Put your device into recovery mode.
  • For iPhone 8 and later models: Press and release the Volume Up button fast. Press and release the Volume Down button fast. Finally, press and hold the side button until the recovery mode screen appears.
  • For iPhone 7 and 7 plus: Simultaneously press and hold the Volume Down button and the side button until you see the recovery-mode screen.
