SMS Opt-In Compliance Documentation
Use the following text on your website (e.g., on your "Contact" or "Terms" page) and when submitting your Toll-Free Verification application to Telnyx.

1. Verbal Opt-In Script (The "Call Flow")
Description: Users initiate the opt-in by calling our customer service number. Upon calling, the Interactive Voice Response (IVR) system informs the user that a text message will be sent if they need to complete a payment to proceed.

The Script:

Caller: Dials +1-866-596-9687. System: "Thank you for calling The Unsecure Signal. Your call is being routed." [System checks payment status] System: "You have been sent a text message with a payment link. Please pay and call back. Goodbye." [System sends SMS immediately after playing this message]

2. Website Disclaimer (Put this in your footer or contact form)
Even with verbal opt-in, you should display this standard legal text near your phone number on your website:

"By calling or texting +1-866-596-9687, customers agree to receive text messages for service status and payment notifications. If you no longer wish to receive text messages, you may opt-out at any time by replying 'STOP'."

3. Privacy Policy Snippet (Required for verification)
You generally need a Privacy Policy link. Ensure it includes something like:

"No mobile information will be shared with third parties/affiliates for marketing/promotional purposes. All other categories exclude text messaging originator opt-in data and consent; this information will not be shared with any third parties."
