What do cell phones do?

Like a home phone, a cell phone can make calls to other phones. A cell phone can also sent text messages to other cell phones compatible with the text messaging application. Cell phones also have other various applications, such as Bluetooth, alarm clocks, (video)camera, calculators, stopwatches, calendars, and more, depending on what your phone is compatible with.

All phones have default ring tones and message tones, but other ring tones can be purchased. When you set a tone as your ring tone, the sound you chose will play when someone calls your phone; you can also set certain ring tones to certain people in your contacts list. When you set a tone as your message tone, the sound you chose will play when someone sends you a text message. Your phone can also be set to a vibrate mode so that the phone will vibrate when someone calls you or sends you a text message; or it can be set to silent so that it will make no noise no matter who call/text messages you.
