The problem with an open network
Application-to-Person (A2P) and Machine-to-Machine (M2M) messaging are growing sources of revenue for mobile operators. However, many operators leave the door open for other operators to flood their network with text messages, missing out on valuable termination fees. While the sending operators collect substantial revenues for the traffic, the operator that actually delivers the message is left without compensation.
As messages from foreign SMSCs are delivered directly to subscribers, operators are generally unable to adequately control incoming traffic. This lack of control exposes customers to spam and fraudulent messages which can directly impact their satisfaction. Illicit traffic also increases the load on customer services and as the amount of irrelevant SMS messages increases, SMS itself becomes less efficient as a marketing channel, further compounding the loss of revenue.
Drive new revenue and protect your subscribers
Sinch offers a product and service portfolio that enables operators to control the flow of messages, protecting revenues, subscribers and maintaining SMS as a premium marketing channel. Our SMS Firewall is developed using our extensive experience in SMS and A2P messaging with a rules-based system which allows you to carefully control the traffic that’s transported through your network.
Our SMS Firewall combined with the Sinch SMS Firewall Update Service gives you full control to maximize your revenue from A2P traffic and protect your subscribers.
