Working on-the-go nowadays usually means a laptop or tablet with mobile broadband access—either through tethering your mobile device or a separate dongle with a mobile broadband plan. In most situations, WiFi tethering your phone would be enough. However, if you do require extended periods of time connected to the Internet, you might be able to save yourself some battery and convenience with a USB 3G adapter. However, what do you do if your tablet isn’t compatible with your dongle?
Well thankfully, XDA Senior Member Bhaskar1109 has figured out a way of bypassing this incompatibility, allowing for any 3G broadband dongle to connect to any rooted Android tablet. A process that may seem a bit daunting to some, it requires ES File Explorer to be installed with root access and terminal software on your PC and tablet.
To accomplish this, you must install an APK on your tablet, as well as run two scripts that are available in the guide. Bhaskar1100 has included screenshots for extra guidance, and he has also acknowledged a small bug where the mobile broadband icon is not displayed in the status bar. However, this won’t affect functionality.
