Another feature of Opera Max - Data Manager is app monitoring. Thanks to this feature, users can find out at any time how much data each app installed on their Android device is consuming and can also, of course, cut off any app that is using more than its share.
The combination of these two features (video compression and app monitoring) lets you not only watch loads of YouTube videos using 3G, but also control your device's data usage so that you never run out before the end of the month.
Opera Max - Data Manager is an excellent data control tool that makes it so you'll never be left hanging without 3G at the end of the month.
Requires Android 4.0 or higher
