The very first thing you want to do is to check Apple’s System Status page. That way you’ll know if the App Store is down or under maintenance. It’s very rare that could happen but it has happened before where both the App Store and Apple Music have been down.
The App Store is the very first service listed on this page. A green dot to the left of the App Store means that service is operating normally. If you see a gray square, it means the service is under maintenance.
If the store is down, there’s not much you can do except to wait for Apple to fix the problem. But if the App Store is not down, you know the problem is with your iPhone.
2. Check Internet Connection
First, you want to make sure your iPhone has a reliable internet connection. A simple way you can check this is by opening a site through your favorite web browser. If the page can’t load that means your iPhone is not connected to the internet. Follow these troubleshooting tips below.
When you’re having trouble with connections on your phone and you’re struggling to get a signal turning off and on Airplane mode can help. By doing so you’ll disable and re-enable your device’s cellular radio, Wi-Fi, and Bluetooth. Depending on what iPhone you own you’ll either swipe up or down to bring up the control panel where you can turn on and off Airplane mode.
Rebooting your router can fix your internet connection issues. Unplug your router and modem from power, then wait for 30 seconds and plug them back in.
3. Reset your network settings
If all else fails, you’ll need to reset your network settings and see if that fixes the problem. Go to Settings > General > Reset Network Settings. Keep in mind this will erase your network settings such as your Wi-Fi passwords.
This is a basic—but effective—troubleshooting step you should use whenever you experience problems with your iPhone. Restarting your device can help with many bugs your device may have. To restart your iPhone go to Settings > General > Shut Down.
You can also use these combination buttons depending on what iPhone model you own. For iPhone X and later, press and hold either volume button and the side button until you see the power off slider.
If you own an iPhone SE (2nd generation), iPhone 8, 7 or 6, press and hold the side button until the power off slider appears.
For iPhone SE (1st generation), iPhone 5 and earlier, press the top button until you see the power off slider appears. Wait a few minutes before turning on your iPhone again.
5. Update your iPhone to the latest iOS release
An outdated iOS can cause your iPhone to not function properly. That’s why Apple pushes new updates regularly. Ensure that your iPhone is running the latest iOS version. Go to Settings > General > Software Update.
If there’s any update available, download and install it to your iPhone. Remember to turn on Automatic Updates, so your iPhone can automatically install software updates overnight.
6. Sign out and sign in again
Sometimes a simple trick can fix big problems. Why don’t you try to log out and then log back into the App Store on your iPhone – and see what happens:
Go to Settings > iTunes & App Store.
Tap on Apple ID at the top of the screen, then select Sign Out.
Log in again using your Apple ID and password.
7. Potential Hardware Problems
If all else fails, your iPhone may have a hardware problem, which prevents it from connecting to the internet. In that case, your best bet is to set up an appointment at your local Apple Store. They should be able to narrow down the cause of your iPhone issue.
