Why can't Apple phone download AOEX

Unable to download the software solution:
1. Check the network: If the Apple store shows that the App
store cannot be connected, you need to check the network settings of the mobile phone first. See if there is any opening WiFi and mobile data network. In addition, you need to pay attention to whether the flight mode is turned off. If the icon of the upper right of the mobile phone has an aircraft logo, please turn off the flight mode.
2. Check the account: Use Apple mobile phone to download the app to have your own Apple account. If you ca n’t download it, you need to check whether your Apple account password is wrong and the app paid. If you pay, you need to charge it to the account to download.
3, bill questions: Maybe few people will encounter such problems, but such problems also exist. That is, the apple display account has a bill problem and cannot download any app, asking us to update the bill information and payment methods. In the case of this situation, don't worry, just change a valid and rich payment method to wait for its money to deduct.
4. Check the memory: The app that cannot be downloaded may be that our mobile phone is full. Uninstall some of the uncommon apps.
