## Troubleshooting

### Common Errors

| Error | Cause | Solution |
|-------|-------|----------|
| `Brand verification required` | Sole proprietor brands need phone verification | Check email/SMS for PIN, run `telnyx 10dlc brand verify <id> --pin <code>` |
| `Campaign rejected: insufficient description` | Description too vague | Be specific about message purpose, include business context |
| `Sample messages must include opt-out` | Missing STOP instructions | Add "Reply STOP to unsubscribe" to sample messages |
| `Phone number already assigned` | Number linked to another campaign | Run `telnyx 10dlc unassign +1...` first |
| `Brand pending` | Still under review (24-72h typical) | Wait and check status with `telnyx 10dlc brand get <id>` |
| `Invalid use case for sole proprietor` | Some use cases restricted | Sole prop limited to: 2FA, CUSTOMER_CARE, DELIVERY_NOTIFICATION, ACCOUNT_NOTIFICATION |
| `Rate limit exceeded` | Too many API calls | Wait 60s and retry |
