Just in case you don't already know. If you have apps or in my case games that require wifi for them to work such as Modern Combat 5 on multi player mode. There is an xposed module that will allow you to make the game(s) think you are on wifi. The module is called "Fake Wifi Connection". Thanks to lemonsqueeze for making it.
Install the xposed FRAMEWORK (requires root) from below. Then search for the Fake Wifi Connection module and install it. Open the module and select the app or game you want to enable the module for and save it. That's it. Enjoy multi-player on 4g or lte.
