Several users have reported that they are having problems enabling cellular data for apps. Some users have said they turn on cellular data for apps but then cellular data keeps turning off itself.
It appears that cellular data for all apps or individual apps does not stay on and keeps itself disabling. Some apps on your iPhone may require cellular data to operate normally at all times. This setting on your iPhone can be found in Settings > Cellular.
Are you experiencing this problem too? Then this article is for you. This can be an important problem. To explain more, you turn on cellular data for apps but this is not respected by the iOS system. This will prevent you from using your apps because these apps will fail to connect to mobile data or access cellular data. For example, if the affected app was Apple Maps, you will not be able to use it when you need it. This is because they will stop functioning unless there is a Wi-Fi connection available.
