Starting with Android 4.4 KitKat, Google added a code that tags your internet traffic when using mobile hotspot on Android. This has made it easy for carriers to block Wi-Fi tethering on devices if it is not included in your usage plan. However, it is much easier to unlock Wi-Fi tethering on Android 6.0 Marshmallow, since the coded tag has been removed.

In order to use portable Wi-Fi hotspot on your carrier restricted Android, you need to edit the build.prop file. Hence, you need a rooted device to unlock Wi-Fi tethering on Android, along with a root-enabled file manager.

Step 1: Install a root-enabled file manager

To activate Wi-Fi hotspot on your Android, you need to edit the root directory of your device. There are plenty of Android file managers that you can find on the Google Play Store to get this done.

Step 2: Edit the build.prop file

Once you have downloaded your preferred root-enabled file manager, open it and grant it Superuser permission. Go ahead and navigate to the root partition of your device, which is the highest folder in the folder tree. From the root directory, access the “System” folder and make sure that the directory is mounted as read/write (Mount R/W).

Scroll down to the bottom of the folder to find a file named “build.prop” and long-press it. On the “Options” menu that appears, press “Open with” and then select “Text Editor” from the pop-up window.

Once you have the “build.prop” file open in the text editor, scroll down to the bottom of the list and press enter on the keyboard. In order to activate the hidden multi-window in Android Marshmallow, you have to insert this line of code into the file:
