Turn it on under Product settings → Sales Agent → SMS.
Getting a number
Enabling SMS provisions a dedicated phone number for your dealership automatically. While that is in progress a warning appears in the Status section. Once ready, the number is shown next to the toggle.
You can flip the toggle on before the number finishes provisioning. SMS starts working once the number is assigned.
How it differs from website chat
Text is a plain-text channel, so some things work differently:
Pre-qualification links
The agent puts the link directly in the message, for example “Get pre-qualified: https://your-dealership.example.com/…”. There is no “reply YES” step. It is your own branded checkout URL, so the buyer stays in your flow.
If no checkout URL is configured for your dealership, the agent invites the buyer to contact you instead of sending a broken link. Set your checkout URL to enable in-message pre-qual.
Shared memory with website chat
Both channels feed one inbox and share conversation memory. A buyer who chatted on your site last week and texts you today does not start from scratch, and your team sees one continuous history.
Buyers can move themselves from chat to text using the Text us pill, which appears when SMS is enabled.
Compliance
A lead is created once the buyer provides contact details and TCPA consent. Consent gating is built in, not something you configure.
The age and safety guardrail also applies here. When a conversation implies a minor may operate the vehicle, the agent sends a legal notice once per conversation. It cannot be turned off.
