Thanks for utilizing our forums here! I understand that you're having an installation issue with the SlingPlayer for Android Phones and I'll be happy to help you. You would actually want to install the SlingPlayer app on your phone itself. If you did purchase the SlingPlayer for Phones on your tablet, then all you will need to do is log into the same Google account on your phone and install the application!
Hope this helps!
