Use Wi-Fi whenever you can
Connecting your devices to a Wi-Fi network helps you use less wireless data. If your device can't connect to Wi-Fi, it automatically switches back to cellular data.
Did you know? Some apps on your device use wireless data even when connected to a Wi-Fi network.
Explore our interactive device tutorials on how to:
Take control with Stream Saver
Stream Saver conserves data by detecting video content and streaming it in standard-definition quality (similar to DVD quality, about 480p).
Stream Saver might not support standard-definition quality when 2 or more tethering devices stream video from the same app or website at the same time. If you experience slow speed, you may want to use a different app or website on each device. Or, turn off Stream Saver. Learn how to manage Stream Saver for your devices
Use built-in device features
Most smartphones and tablets have built-in data-monitoring features. You may also be able to set usage warnings or limits to disable wireless data when you've used a certain amount.
