SMS lets your business send and receive text messages from numbers you own. In the US, texting from a standard 10-digit number requires A2P 10DLC registration: every organization registers its own brand and campaign with the carrier registry before any message can be sent.
SMS registration is handled in the dashboard, not the API. Carrier registration (TCR) is compliance-critical — the guided flow validates your details, runs a free compliance review, and walks you through approval so a submission can’t be wrong before you pay the activation fee. Sending stays gated until your campaign is approved.

​
Set it up

  1. Open SMS in the dashboard.
  2. Enter your business details — the platform auto-generates compliant campaign text (sample messages and opt-in language).
  3. Run the free compliance review (green / yellow / red, with specific fixes).
  4. Submit once it’s green. This pays the one-time activation fee and registers your brand and campaign with the carrier registry; status then updates as the registry approves it.
  5. Enable SMS on the numbers you want to text from.

​
After approval

Once your campaign is approved, your agent can send and receive texts on its enabled numbers. Opt-outs (STOP) are honored automatically, and the dashboard keeps a do-not-text suppression list — re-enabling a number requires fresh, documented consent.
Plan the registration step before launch — approval is controlled by the carrier registry and can take time, so start it early.
