Article: You'll usually find this receiver-shaped app icon on the Home Screen. Many carriers have a code or a number that you can dial to turn off your voicemail feature (or request that it be turned off). If your Phone app doesn't open to the dial pad, tap the dial pad tab to open it.  It's the icon with 9 squares. Using the dial pad, type in one of the following codes or phone numbers depending on your carrier:   Verizon - (800) 922-0204   Sprint - *2   AT&T - 611   T-Mobile - 611 This is usually at the bottom of the screen. In most cases, you'll have to select a language, wait for a "Voicemail" or "other inquiries" section, and then speak to a customer service representative about disabling your Android's voicemail. You may be asked for your voicemail PIN, account password, and/or other credentials. When the customer service representative or automated service confirms that your voicemail has been disabled, it's okay to hang up.

What is a summary?
Open your Android's Phone app. Open the dialer page. Enter a code. Tap the "Call" button. Follow any spoken instructions. Make sure not to hang up until your voicemail is turned off.
