How do I minimize my data usage?
Since data sent/received over Wi-Fi networks does not count toward your monthly usage, it's good practice to use Wi-Fi wherever available. Using Wi-Fi at home is an obvious example, but many offices and public spaces also offer Wi-Fi networks that can be used too.
Set your handset's Wi-Fi Sleep Policy to "Never"
Certain phones may disconnect the Wi-Fi network when not in use. You can force your handset to always use Wi-Fi (when available) by choosing Settings > Wireless and Networks > Wifi Settings > Press "menu" and choose "Advanced" and then change the Wi-Fi Sleep Policy to "Never". This is not the only pathway to finding this feature in your phone. To find directions specific to your phone, check your device's manual.
Alerts and Usage Caps
In addition to the previous tips, you can also set alerts and usage caps to help track and reduce your data usage.
Important information about Alerts and Caps
You should generally set an alert or cap for a little bit before when want to be notified. For example, if you want to be alerted when you hit 200MB, it's ideal to set that alert for around 180MB. This takes into account the time it takes for the data information to be sent back to us so we can send the alert to you.
Alerts and hard caps for voice don't go into effect until you've finished the call you're on.
If your device is in the middle of a data session or a process that uses data (i.e. downloading a file, watching a continuous play list of videos or an app running in the background) that process will need to complete before an alert is sent or a hard cap kicks in.
In some cases, usage information can take up to 48 hours to be updated. This has been seen with data and voice/text when roaming.
