1.Buy an SMS-capable number in the Twilio console (Phone Numbers → Buy a number).
2.US sending: register for A2P 10DLC (Messaging → Regulatory compliance) — carriers filter unregistered traffic hard.
3.In FrazzleCRM: Settings → Credentials → Add Twilio — paste Account SID, auth token and the From number.
4.Drop a Send SMS step on any flow and pick the credential. Reminder templates (24h/1h) are in the No-Show Killer template.

You pay Twilio directly — roughly a cent per segment in the US. FrazzleCRM adds no per-message markup on any plan.

For US traffic, effectively yes — unregistered long-code SMS gets filtered aggressively. It's a one-time registration through the Twilio console.
