I couldn’t download from the AppStore

Hi,

Sorry to hear you are having issues with downloading apps on your iPhone.

First, I would recommend updating to iOS 15.2.1 within Settings > General > Software Update.

• Update your iPhone, iPad, or iPod touch
• How to update to iOS 15 or iPadOS 15

If the issue persists after the update, the following articles should be able to further assist:

• If you can’t download or update apps on your iPhone or iPad
• If you can't connect to the App Store, iTunes Store, or other Apple services
• If your payment method is declined in the App Store or iTunes Store
• Redownload apps and games from Apple
• If there's an issue when you redownload apps, movies, or other content from Apple
• If your Apple ID is locked or disabled

Some things you can try. Do you have access to another WiFi network where you can try? That has worked for several people.

Try a restart.

Restart your iPhone, iPad, or iPod touch    *

Try a forced restart. See the section towards the end of the article.

Reset Device. -

If necessary

Hard reset.     -

Do a backup and try a factory reset. Then restore from your backup.

Restore to Factory setting.      *

Restore - If you see an error when you update or restore your iPhone, iPad, or iPod.   *

Backup - Restore your device from an iCloud or iTunes backup.     *
