Key Takeaways
- Scenario 1100 is a custom-hostname CNAME inbox: inbound YES cuts DNS at freeze — never SMS the TXT token. Not API-key rotate, DPA sign, or domain-unlock ACK.
- A YES that never lands is a hostname still on the old host and a TLS desk that thinks it flipped.
- Do not SMS TXT tokens, zone files, or registrar OTPs. Short confirm + ticket link.
- Console OTP stays on another device.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free: 1 device / 300 SMS lifetime / 300 contacts. Developer: 25,000 SMS per year.
Android SMS gateway scenario 1100 is an onboarding DNS desk. Outbound asks “cut CNAME tonight? Reply YES.” Inbound YES arms the freeze. API-key rotates are the wrong list.

CNAME cut, not API key
One outbound, one inbound match. Map the reply to the DNS ticket, not a key rotate.
If YES arrived and you had already texted the TXT token, you handed a zone secret to whoever held the SMS.
