Mobile data is always important for Android and iPhone users. Phone service isn’t cheap, and HD video and more is always available to stream in your pocket, making it easy to push your data limit.
To have your Android phone warn you when you are approaching your data limit, go to » Settings»> «Data Usage» . Here you will see the current data usage on the graph — see the line with the number next to it? Drag this to where you want to set the monthly alert — 75% of your total is probably a good number.
To make sure this is being measured correctly, make sure your billing cycle is accurate right above the chart. Tap the dropdown and select Change loop…, to define start and end dates. Please note that your phone’s measurement is not official and may differ from your carrier’s records.
This tool is great for estimating, but plan some wiggle room just in case.
