What is WAP & Carrier Billing Traffic?

WAP and carrier billing traffic (MO/MT) is legacy mobile monetization: users subscribe to content via SMS/USSD, charged on their phone bill. Click-WAP → landing → confirm SMS → recurring billing. Peaked 2000–2010; now niche GEOs (Africa, MENA, parts of CIS).

Scheme

Aggregator plus mobile operator; high churn, regulatory scrutiny. Many flows are grey-hat. Google Play billing dominates apps — WAP for web/content.

Arbitrage today

Antivirus subs, horoscopes, adult content — declining but present. Strict local telecom rules; operator caps. Formal CR is high; rebill and refunds are risky.

Tracking

Operator postback; sub by affiliate/portal. Reconcile with chargebacks and unsubscribe rate.
