Prepayment Funding for SMS Firewall & Exclusive Termination Deals

Exclusive A2P gateway agreements are increasingly used by mobile network operators to secure their networks, reduce fraud, and monetize international A2P traffic. In these arrangements, a single partner manages and terminates all inbound messaging traffic, replacing fragmented multi-aggregator routing.

Exclusive gateways provide revenue protection by shutting down grey routes, implementing advanced anti-fraud tooling, and enforcing high-quality delivery for OTPs and critical notifications. Many agreements also cover A2P voice/flash calls alongside SMS for omnichannel security and compliance.

SMS firewall gateways sit at the core of this model. They classify traffic in real time, filter spam and phishing, enforce licensed routes, and provide analytics that drive accurate billing. This preserves operator revenues while improving subscriber trust and network performance.

SMS firewall deals typically require the deploying operator to aggregate inbound market traffic, commit to minimum monthly volumes, and prepay for capacity over 6 to 24-month terms.
