"17941. (a) It shall be unlawful for any person to use a bot to communicate or interact with another person in California online, with the intent to mislead the other person about its artificial identity for the purpose of knowingly deceiving the person about the content of the communication in order to incentivize a purchase or sale of goods or services in a commercial transaction or to influence a vote in an election. A person using a bot shall not be liable under this section if the person discloses that it is a bot."
(b) “Online” means appearing on any public-facing Internet Web site, Web application, or digital application, including a social network or publication.
SMS could be a considered a "digital application", so it might apply. Agree that it could use clarification.
