There are many reasons for the problem of "unable to connect to the iTunes Store", and we have solved it step by step.
First, the solution to the problem that itunes store can't connect due to network failure
1. If your mobile phone uses 3G mobile data to access the Internet, please make sure that the cellular data has been downloaded from Settings >; Open in cellular data.
2. If your mobile phone uses Wi-Fi to surf the Internet, please check whether your WiFi connection is normal. You can use other devices that can connect to your Wi-Fi (such as other mobile phones or laptops) to see if you can connect to the network and access the Internet. If you can't connect to your wifi normally through other devices, please restart the wireless router, and then click Settings-> WiFi on the phone desktop > Enter the current WiFi–> ignore this network to reset the current WiFi, then restart the iPhone and connect the wifi again.
If the mobile phone can connect to the wireless network normally through the above methods, reopening the app store should solve the problem of being unable to connect. If you find that it is not a network problem that prevents you from connecting to the iTunes Store, please refer to the next step.
3. Exit the App Store in the background, go to Settings → Wireless LAN to find your WiFi, click the exclamation point to the right of the WiFi name, click Enter to find DNS, change the DNS data to 8.8.8.8, and then open the App Store to see if it can be connected normally. If the problem is still not solved, please see the next step.
Second, the solution that the phone setting problem makes it impossible to connect to the itunes store
1. 1. Restore network settings —— Go to Settings > General > Restore > Restore network settings of iPhone5s, and the device will restart. After restarting, open the app store again to see if it can be connected normally. If not, please see the next step.
2. Reset access restrictions-Go to Settings–> General–> Access Restrictions of iPhone5s, turn on access restrictions for 5 seconds, and then turn off access restrictions. After restarting, open the app store again to see if it can be connected normally. If not, please see the next step.
