Optimize data usage
Data usage refers to the amount of data uploaded or downloaded by your device during a given period. Depending on the device and your wireless plan, you may be charged additional fees when your data usage exceeds your plan's limit.
To monitor your data usage, adjust your data usage settings. First check your plan and determine what data limits may apply.
Warning! The usage displayed on the data usage settings screen is measured by your phone. Your carrier's data usage accounting may differ. Usage in excess of your carrier plan's data limits can result in steep overage charges. The feature described here can help you track your usage, but is not guaranteed to prevent additional charges.
Data usage settings allow you to:
GSet the data usage level at which you'll receive a warning.
GSet a data usage limit.
GView or restrict data usage by app.
