Homer is seen talking on a cell phone in a prison. Using a mobile device in a prison, such as a cell phone, is illegal in the United States under Federal Law. That rule applies to all prisoners, staff and visitors. And the law applies to all Federal, military, state and county prisons and jails in the United States.
Mobile phones are one of the most smuggled items into prisons. They provide inmates the ability to make and receive unauthorized phone calls, send email and text messages, use social media, and follow news pertaining to their case, among other forbidden uses.
