In practice, compliance rests on evidence. The question is never "did you mean well", it is "can you show, for this specific phone number, when and how consent was captured, and that STOP was honoured immediately". That means storing the timestamp, the source of the opt-in, the exact disclosure wording shown, and the full opt-out history for every contact.
Message content matters too. Carriers filter for prohibited categories regardless of registration, and every campaign should identify the sender, keep to the use case it was registered under, and honour HELP and STOP keywords. Sending marketing traffic through a campaign registered as transactional is a common and avoidable violation.
- Two layers: carrier registration (10DLC) and legal consent (TCPA). Both are required.
- Prior express written consent is required before marketing texts, with a clear disclosure at opt-in.
- STOP and HELP must be honoured automatically, and opt-outs must persist across channels.
- Traffic must match the use case its campaign was registered under.
- On SimplyRCS, STOP and HELP are handled above the AI layer, so they are always honoured, and consent records are retained with a full audit trail.
