Short Message Service Center (SMSC)

A Powerful, Yet Cost-Effective SMS Center Solution

Modulo’s Short Message Service Center (SMSC) is a carrier-class high-performance SMS Center for GSM/UMTS networks with features for MNOs, MVNOs, and Fixed Line Operators.

It is a fully scalable, software-based, and cloud-ready solution which performs intelligent handling of SMS traffic in 3G GSM/UMTS networks.


Small MVNOs depend on their host network for many of their network functions. As their subscriber base grows, many MVNOs want to retain more control of their network and lower their OpEx to facilitate faster growth. Deploying a reliable, scalable and cost-effective SMSC is a great opportunity for expanding MVNOs to decrease their dependency on their host network, lower their operating costs and increase revenue by offering competitive and differentiating SMS Services to customers.


The ongoing, fast-paced growth in mobile data traffic warrant significant changes in mobile network architecture. MVNOs that want to keep up with the frequent changes will have to adapt. Mobile operators will need to be more flexible, more easily and quickly scalable and more cost-effective. Modulo’s SMSC solution can be deployed on any standard Linux server or on any popular cloud service, such as AWS, Microsoft Azure, and Google Cloud.


Our SMSC has a simple and easy to use RESTful HTTP API, which provides unlimited flexibility in regards to developing additional services based on the SMSC. This saves operators and OEMs the high costs involved in developing SS7 based applications, by enabling web developers to create specialized SMS-based services for the mobile network.
