Fliff: VoIP vs real carrier (what sells)
Fliff risk engines classify numbers as mobile, landline, or internet telephony. Shared VoIP ranges are cheap to burn and frequently blocked — which is why Fliff verification fails on TextNow-style apps.
RealNonVoipUSNumber sells carrier-backed non-VoIP inventory for Fliff. Fresh lines per order reduce reuse flags, and pay-per-success billing keeps Fliff OTP costs predictable when you scale.
