A2P Monetization

Mobile Network Operators (MNOs) primarily rely on data, voice, and SMS services for their business operations.

Despite the rapid growth of the global A2P SMS messaging market, International Inbound A2P SMS is often overlooked.

The market has seen substantial growth, from $12 billion in 2017 to $27 billion in 2022.

Revenue losses due to gray international routes amounted to $6 billion in 2018, prompting more MNOs to deploy SMS Firewall Solutions.

However, simply installing an SMS Firewall may not be sufficient to address revenue leaks, as MNOs struggle to fully control international A2P traffic. This challenge may be attributed 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
