does cellular data in settings have to be turned on all the time?
iPhone 6 Plus
No, not unless you need a data connection and there is no wifi available.
without wifi or cellular data though, your iPhone is just a basic cellular telephone.
No. Whether you need it on all the time depends on what you want to do and if you have other data sources. -AJ
not really, and you can disconnect it from setting>cellular>switch "Cellular Data" off. but if you want it to be connected only when the wifi is weak make sure you turn it one and go to setting>cellular>switch "Wi-Fi Assist" on.
No it does not. You can go into settings, tap "Cellular", and press the tab next to "Cellular" to turn it off
