You can do it for free easily, just disassemble your phone and unhook the antennae and attach five 12v batteries. What this does is it amplifies the phone and increase the wavelength making it possible to pick up Direct TV waves. All you need to do now is turn on your phone and instead of seeing the reception bars you will see numbers. All you have to do now is type in **#786**(The numbers on the screen go here). What happens next is an app that is saved in your phone appears called "Phone Direct". From this program you can watch TV for free!
Direct TV was going to try a new cell phone service but it never took off, that is why you have the app.
This is also similar to how phones with GPS work, GPS however doesn't need as long as a wavelength as satellite TV does so it is able to change your phones frequency with the battery. Thats why your cell phones battery drains so fast when its using the GPS
