A2P Monetization

Mobile Network Operators’ (MNO) business rely mainly on data, voice, and SMS.

International Inbound A2P SMS is usually neglected which is strange, considering the fast pace of the global A2P SMS messaging market growth: from $12 billion in 2017 to $27 billion in 2022.

With revenue lost to gray international routes costing the A2P messaging industry $6 billion in 2018, more and more Mobile Network Operators (MNOs) are deploying SMS Firewall Solutions.

The problem is that merely installing an SMS Firewall is not enough to close revenue leaks as MNOs continue to struggle with fully taking control over international A2P traffic. This may be due to:

Incomplete awareness of businesses generating A2P traffic

Inability to monitor all the services and how they are currently delivering traffic

Lack of direct connections to businesses who are generating A2P traffic

Lack of an integrated team and effective procedures
