Is opt-in needed to send RCS messages?

You need a consumer to opt in before you send RCS messages, but the good news is that if they've opted into your SMS program, that opt-in generally covers the same program switched to RCS.

You're responsible for giving users a way to opt out, and to follow through when they do. If someone opts out of your RCS messages, that opt out should apply to the same SMS program too.

Be sure to check local laws and best practices for handling opt-out requests the right way.

Note: Google requires that when someone says they want to stop getting messages, your agent needs to respect that. Opt-in and opt-out need to be demonstrated for all RCS Agents, even if local carriers and regulations do not require them.
