Protect business-critical messages and ensure A2P monetization

Unwanted messages sent via unauthorized channels mean lost revenue, as well as higher network costs due to increased traffic. SMS+ is a complete SMS solution from one provider that protects, filters and terminates all text messages via the ICSS SMS hub, while actually generating revenue. It requires no OPEX or CAPEX for equipment, as it runs completely in the SS7 cloud.

Unlimited and cost-effective messaging, worldwide

Today’s tech-savvy consumers want unlimited use of their mobile devices, no matter where they are. ICSS matches their expectations for seamless, instant connectivity, independent of location. For best-in-class international operability, we offer our reliable person-to-person messaging solutions (SMX and MMX), that make it easy to expand your global messaging footprint.

The Solution

SMS fraud is a costly problem for mobile operators. Our SMS+ is an SS7-based dynamic authentication solution that identifies and blocks SMS spams, spooks, fakes, floods and ghost messages. As opposed to static authentication tools, it detects the continually changing behavior of grey route traffic that bypass termination fees. In addition, it frees up network bandwidth for revenue-producing traffic, provides higher user satisfaction and helps safeguard your brand reputation.


Recently Deutsche Telekom ICSS joined forces with SMS firewall and A2P filtering specialist Anam. Their combined solution boasts a broad range of dynamic filtering capabilities based on real-time monitoring. The suite of managed services delivers in-depth A2P traffic analysis and reporting, rules management and grey route identification.


  • SMS+ Protect helps operators worldwide by offering protection mechanisms against unpaid use of their network. A unique functionality of this service lies in its ability to dynamically identify and block unwanted SMS messages based on SS7. Most other verification systems are static, and therefore cannot detect the continually changing behavior of grey route traffic.

  • SMS+ Transit provides SMS aggregators with high-quality official routes, and operators with standard termination rates. Direct routes to Deutsche Telekom Group affiliates ensure quick, high quality and verified termination of messages. Additional mobile operators are continuously added to extend the list of networks available.
