Some WiFi internet providers use MAC Address for verification and access to network. You can spoof your system’s MAC address to your Android phone and access internet on mobile.
- Rooted Android Phone
- Any Android terminal application
Open terminal app in phone and type
busybox iplink show eth0
This will show the current MAC address of your phone.
busybox iplink set eth0 00:00:00:00:00:00
replace 00:00:00:00:00:00 with your required MAC address.
If you have installed busybox from Titanium Backup program, you can access busybox from following directory.
/data/data/com.keramidas.TitaniumBackup/files/busybox iplink show eth0
Above steps are tested and working in Nexus S.
Update : For Samsung Galaxy S2
Use following command (It is same as the command we use in GNU/Linux). Thanks to orestis46
