# 30570: Call-to-Action is missing customer support instructions

Log Type: APPLICATION

Log Level: ERROR

## Description

This error applies to both Toll-Free Verification and A2P 10DLC registration.

The Call-to-Action (CTA) does not tell consumers how to obtain customer support for the messaging program.

This error concerns support instructions in the CTA. For support information missing from Terms of Service, see [30560](/docs/api/errors/30560). For Toll-Free automated HELP-response requirements, see [30486](/docs/api/errors/30486).

### Possible causes

* The opt-in disclosure does not include HELP instructions.
* Support information appears in Terms of Service or the automated HELP reply but is absent from the CTA.

### Possible solutions

* Add clear customer support instructions to the CTA that reference the HELP keyword, for example "Reply HELP for help". This example illustrates the support element only, not a complete compliant CTA.
* Provide updated evidence showing the complete CTA for registration review.
