"My iPhone 7 was showing no service and said cellular data could not be updated. I reset to factory setting and now it is telling me unable to activate. I connected to my Mac, then iTunes, and the message I got while using the Mac is that the iPhone could not be activated because the activation information could not be obtained from the device."

Seeing the error "iPhone could not be activated because the activation information could not be obtained" can be frustrating. This error message is quite rare, and if you've encountered it, don't worry. We'll walk you through how to fix it and explain the potential causes, so you can avoid running into this issue again. Let's look together.

There are several reasons why the activation process may fail. Below are the possible causes for the "iPhone could not be activated because the activation information could not be obtained" error.
* Unstable network connection (issues with Wi-Fi or cellular data).
* Apple servers are busy or experiencing outages.
* Your device may not be compatible with the carrier SIM card currently inserted.
* Activation Lock could be enabled through Find My iPhone.
* The iOS version on your iPhone may no longer be supported by Apple's servers.
* The iOS firmware might not have been installed correctly on your device.
After you know the reasons, let's go over some solutions that should help resolve this activation problem on your iPhone.
When activating an iPhone, the device must be connected to a stable network to communicate with Apple's servers. If the connection is unstable, it may fail to obtain the activation information.
Make sure you're connected to a reliable Wi-Fi network. Try switching to a different Wi-Fi network, and if that still doesn't work, attempt activation using cellular data instead.
Sometimes, the issue isn't on your side. Apple's activation servers may be temporarily down, which can trigger your iPhone could not be activated because the activation information could not be obtained.
To check, visit Apple's System Status page and look for the "iOS Device Activation" indicator. If it's green, the service is working normally. If it appears yellow or red, the activation service is currently unavailable. In that case, wait until it turns green and then try again.

Temporary system glitches can prevent activation. A force restart refreshes the system and can resolve minor bugs causing the issue.

Your iPhone may need a valid SIM card to complete the activation process. If the SIM card is damaged, improperly inserted, or not recognized, the activation may not go through.
To fix this, turn off your iPhone and use a SIM eject tool to remove the card. Check it for any damage or dirt, then reinsert it or try a different SIM card. Power your device back on and attempt activation again. If it still doesn't work, contact your carrier for assistance.

The error message "the iPhone could not be activated because the activation information could not be obtained" may also appear if you are using an outdated version of iTunes. If you haven't updated it recently, make sure you install the latest version on your computer before connecting your iPhone.
To update iTunes, follow the steps below:
Step 1. Launch iTunes on your computer and make sure it has fully loaded.
Step 2. At the top of the iTunes window, click the "Help" menu, then choose "Check for Updates" from the drop-down list.
Step 3. If an update is available, a prompt will appear. Follow the on-screen instructions to download and install the latest version of iTunes.

To resolve the "iPhone could not be activated because the activation information could not be obtained" issue, you can also try restoring your device using DFU mode via iTunes or Finder. Please note that this process will erase all data on your iPhone. (How to back up iPhone data?)
Here is how to do it:
Step 1. First, open iTunes or Finder if you're using macOS Catalina or later and connect your iPhone to the computer.
Step 2. Then, put your iPhone into DFU mode. Once your device is in DFU mode, the screen will remain completely black.

Step 3. Your iPhone should be automatically detected, and a pop-up will appear on your computer. Click "Restore" and confirm your choice to begin the process.
Step 4. After the restore is complete, you can set up your iPhone and restore your data from your most recent backup if available.
