Which rule prohibits automated calls to mobile phones without consent?

The Telephone Consumer Protection Act (TCPA) is the correct answer as it specifically addresses the issue of automated calls, also known as robocalls, to mobile phones. Enacted in 1991, the TCPA restricts telemarketing calls, including the use of prerecorded voice messages and automatic dialing systems, without prior express consent from the called party. This legislation was designed to protect consumers from intrusive telemarketing practices, especially on mobile phones, where the cost and potential invasion of privacy are heightened.

The Robocall Rule, while related, primarily focuses on enforcing provisions against unwanted robocalls but does not exclusively prohibit automated calls without consent. The Telemarketing Sales Rule is more focused on telemarketing practices overall rather than specifically addressing automated mobile calls. The Consumer Rights Act, while important in the context of consumer protection, does not specifically address consent regarding automated calls. Thus, the TCPA is the most relevant regulation when it comes to prohibiting automated calls to mobile phones without prior consent.
