My AppStore

Hi,

I would recommend taking a look into the following resource for further support:

• iPhone 7 Repair Program for "No Service" Issues

If this does not apply to you, I would recommend these resources instead:

• If you can’t download or update apps on your iPhone or iPad
• Manage App Store purchases, subscriptions, settings, and restrictions
• If you can't connect to the App Store, iTunes Store, or other Apple services

Check the range of the mobile network, see this Apple article: If you see No Service or Searching on your iPhone or iPad

If you see No Service or Searching on your iPhone or iPad - Apple Support

Check also the Wi-Fi network, see the following Apple articles:

Connect to Wi-Fi on your iPhone, iPad, or iPod touch

Connect to Wi-Fi on your iPhone, iPad, or iPod touch - Apple Support

If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network
