## Add-on A — A2P Messaging (10DLC)

**Required if** the partner is sending A2P (application-to-person) messages. Slots in alongside **Phase 3 — Intelligent Messaging** testing.

| # | Task                                                                                    | Owner   | Notes       |
| - | --------------------------------------------------------------------------------------- | ------- | ----------- |
| 1 | TCR brand registered via Telegent's Sinch DCA path.                                     | Partner | Brand ID    |
| 2 | TCR campaign registered (use case, sample messages, opt-in/opt-out flow).               | Partner | Campaign ID |
| 3 | KYC documentation submitted to Sinch / TCR.                                             | Partner | —           |
| 4 | Campaign approved and bound to partner's `NumberType=mvno` + `MessageType=a2p` numbers. | Joint   | —           |
| 5 | Throughput / TPS confirmed for the campaign tier.                                       | Joint   | —           |

<Note>
  For A2P, use `NumberType = "mvno"` and `MessageType = "a2p"` when provisioning numbers. `iot` numbers are p2p only; `voip` numbers are a2p only.
