Cost-Efficient, High-Performance SMSCNative SMS for 5G Standalone Networks

PAiCore’s SMSC is designed for operators seeking to modernize legacy messaging infrastructure with a flexible, future-ready platform. With the SMSF, the same platform delivers native SMS within 5G Standalone networks.

OVERVIEW

PAiCore’s SMSC empowers SMS service providers with a high-throughput, feature-rich messaging platform that boosts operational efficiency through full protocol interworking, including reliable HTTP and SMPP to SS7 conversion. With SMSC CT v3.2.0, the platform further enhances secure connectivity through SMPP over TLS, SMPP and HTTP Proxy Mode, and expanded HTTP authentication capabilities. Unlike closed-box solutions, our open source architecture offers flexible realtime SS7 parameter control via GUI or APIs, allowing customers to optimize delivery & costs.

Built to handle over 100,000 TPS, our SMSC supports modern protocols such as SMPP, HTTP, SS7/SIGTRAN, and Diameter for 4G/LTE deployments. SMSC CT v3.2.0 further improves protocol interoperability with SMPP over TLS, SMPP and HTTP Proxy Mode, and flexible SMPP interface version negotiation. Future capabilities including SIP for IP-SM-GW and HTTP/2 for SMSF/5G continue to expand the platform’s messaging ecosystem.

Our SMSC is backed by high quality 24/7 technical support, which gives our customers the peace of mind that they are not only enjoying a powerful and flexible product with no hidden transactional costs or limiting licenses, but that they can also have access to a capable team that can help them with the initial deployment, training and day-to-day operations as/when needed.

Native SMS for 5G Standalone Networks

PAiCore SMSF enables native SMS delivery within 5G Standalone networks through full integration with the 5G Service-Based Architecture (SBA), allowing operators to deliver messaging services without relying on legacy network components.

By interacting directly with core network functions such as the AMF and UDM over standardized service-based interfaces, the SMSF supports both Mobile-Originated and Mobile-Terminated SMS in a fully 5G-native environment.

Designed to align with cloud-native and service-based principles, PAiCore SMSF simplifies SMS service deployment in modern 5G cores and allows operators to evolve messaging services alongside new 5G use cases.

Short Message Service Function - SMSF (2026) is part of the SMSC Technical Support Plans. See the versions table.
