Do I need cellular data 'on' to load an app?
I am trying to load an app for an interval timer from apple/itunes and all I get is a blank app page. Do I need to have Cellular Data 'on' in order to load an app? I have wireless and blue tooth is on...I have toggled the cellular data button on and off and it makes no difference so far.
Still trying to learn to navigate this phone and it's settings...TIA!
