Does anyone know how to turn off the data on the S3? I usually keep it turned off while travelling to avoid getting charged for roaming.
I have the same problem it logically would be on the "notification bar" with its cousins but it isn't.
I have found it though: Settings > Data usage> Mobile data ( 0=off |=on)
You can make a desktop item to manage data:
Long press on the desktop> Add to Home screen > Apps >Widgets >(long press)Settings shortcuts 1x1 > Data usage.
You can then turn it on and off by clicking data usage.
FYI i have the SGH T999V from Mobilicity
