Automatic downloads in iTunes & App stores UPDATES on In my iPhone 6 iTunes and App stores there is automatic downloads in which my Updates are on. Can I keep these Updates on or shall I turn off to prevent mobile data usage on roaming, or will these updates only happen on Wifi?
It's a configurable option.


  You can also turn Automatic Downloads on or off over your cellular network on an iPhone or iPad Wi-Fi + Cellular. Go to Settings > [your name] > iTunes &amp; App Store and turn Use Cellular Data on or off. Cellular Data downloads are limited to a file size of 150 MB or smaller.
