### Answer Based on the available documentation, I don't see a built-in feature to schedule SMS messages at a specific future time within Retell. The current SMS capabilities include: - **During calls**: Send one-way SMS using the SMS Node (Conversation Flow) or Send SMS tool (Single/Multi Prompt) [(1) ]() [(2) ]() - **Two-way SMS**: Set up chat agents attached to a number for inbound/outbound SMS conversations [(3) ]() - **Outbound SMS**: Use the dashboard's "Make an outbound SMS" button or the [Create Outbound SMS API]() to send messages programmatically For scheduled SMS, you would likely need to implement this externally—for example, using a scheduler (cron job, task queue, etc.) that calls Retell's Create Outbound SMS API at your desired time. Would you like a general answer on how you might approach building scheduled SMS functionality?
