Keep SMS and USSD running strong across 3G, 4G, and 5G
CSG Network Messaging helps operators replace aging SMSC and USSD platforms with less disruption, lower cost, support for legacy networks, 5G migration, and new use cases.
A lower-risk path to modern messaging
CSG Network Messaging helps operators modernize SMSC and USSD, support P2P, A2P, and M2M messaging across 3G, 4G, and 5G, reduce cost, and migrate in stages.
Built for the realities of operator messaging
Unify SMSC, SMS, and USSD on one platform built for continuity, telecom-scale performance, cost control, and phased network modernization.
Unified SMSC and USSD modernization
Replace aging messaging infrastructure with a platform designed to preserve core services, reduce disruption, and simplify migration.
Consolidate legacy SMSC and USSD services onto one modern messaging platform.
Preserve existing self-care, authentication, mobile banking, alerting, and roaming services.
Support like-for-like replacement strategies to reduce migration risk and protect service continuity.
3G to 5G messaging continuity
Keep essential messaging services running across hybrid network environments while preparing for 5G messaging architectures.
Support SMS delivery across 3G, 4G, 5G, and IMS environments.
Enable a stepwise migration path with support for SMSF and USSD over IMS use cases.
Maintain service availability during network transformation instead of forcing big-bang cutovers.
Flexible deployment for lower TCO
Deploy the way your business and network require, from traditional environments to virtualized and cloud-based models.
Support on-prem, virtualized, cloud, and as-a-service deployment options.
Align messaging operations to tighter cost controls and modernization budgets.
Reduce operational overhead with a more productized, lower-touch replacement approach.
High-volume messaging performance
Run critical messaging services at the scale operators need for subscriber, enterprise, and IoT traffic.
Support P2P, A2P, and M2M messaging on a carrier-grade platform.
Handle demanding throughput and availability requirements for business-critical services.
Sustain high-volume messaging use cases without fragmented point solutions.
Integration with charging and monetization
Connect messaging services to the wider revenue stack so you can support monetization, charging, and service innovation more easily.
Integrate with BSS, charging, and external applications.
Support messaging-driven use cases tied to roaming, promotions, and service control.
Create a stronger bridge between messaging operations and commercial outcomes.
Modernize with less risk
Protect critical messaging services
Replace aging platforms without disrupting authentication, alerts, roaming, self-care, and other essential messaging services.
Reduce platform cost
Move off unsupported systems to a more cost-effective messaging platform with lower operational overhead.
Take a phased path to 5G
Support 3G, 4G, and 5G messaging side by side so you can modernize in controlled stages.
Extend service value
Keep SMS and USSD reliable for enterprise, IoT, roaming, alerts, and subscriber self-service as networks evolve.
Aging messaging platforms create avoidable risk
When SMSC and USSD platforms reach end of life, the risk is not just technical. It affects continuity, cost, and the ability to protect messaging revenue.
Replace unsupported platforms with less disruption
Keep high-volume messaging reliable
Create a clearer path to 5G messaging
Flexible implementation
Cloud-native architecture
Support agility, flexibility, and scale with a cloud-native, microservices-based solution.
Vendor-agnostic integration
Integrate with BSS and network components irrespective of vendor or network type, so you are not locked into proprietary approaches.
Step-wise 5g migration
Support migration from 3G and 4G to 5G with less disruption, while continuing to monetize services during the transition.
