If you find yourself in a movie theater, you should place your phone on silent or vibrate mode. This holds true for classroom or business settings as well. Yet, in your day-to-day operations, you can turn your phone to the volume and ring tone of your choice. This way, you can actually hear your phone rather than hope to feel the vibration. All cell phones have a similar method for changing from vibrate-only mode. You should be able to change your phone to the ring tone of your choosing by trying the standard methods.
