iPhone 6s won’t let me sign into App Store or iTunes

Check your connection

Make sure that your device is connected to the Internet. Try using an Internet browser to connect to any website and see if it loads. If it doesn't, use another device on the same network to see if it can connect to any website. If no other devices can access the Internet, turn your Wi-Fi router off and then on again to reset it. If you still can’t connect to your Wi-Fi network, contact your Internet provider for more help. If only your first device can’t connect to the Internet, get help with Wi-Fi on your iPhone, iPad, or iPod touch.

If you use cellular service to connect to the Internet on your iPhone or iPad, make sure that you have cellular data turned on for the iTunes Store, App Store, and Apple Books: Go to Settings > Cellular, and turn on Cellular Data.

Check System Status

Visit the Apple System Status page to see if there are interruptions in service in your country or region.

Update your account

If you're not able to access the iTunes Store, App Store, or Book Store because you can't log in with your Apple ID, learn how to reset your Apple ID password. If you recently changed your Apple ID or password, you might have to sign out and sign back in. To sign in on your iOS device, go to Settings > [your photo] > iTunes & App Store. Tap your Apple ID, sign out, then tap Sign In to log in again. Learn how to sign out on your Mac, PC, or Apple TV.

If you're asked to verify your payment information, make sure that your payment method, first and last name, and billing address are correct and exactly match what's on file with your financial institution.

Update your software

Update to the latest versions of iOS, macOS, tvOS, iTunes, or your PC's operating system. Then try to connect to the iTunes Store, App Store, or Book Store again.

Check the date and time

Make sure that the date and time on your device are set correctly for your time zone.

On your iPhone, iPad, iPod touch: Go to Settings > General > Date & Time. Get more help with date and time.
On your Mac: Open System Preferences > Date & Time.
On your Apple TV: Go to Settings > General > Date and Time.
On your PC: Search for timedate.cpl using the search box or Search charm.

If they're not, set the correct date and time, or turn on the option to set it automatically.

I ask that if you are still not able to logging into the App Store, please let us know more information about your device, and the exact error or message you are getting and we'd glad to continue assisting you.
