Looking for carrier-grade SMSC software that supports SMPP, SS7/MAP and a modern HTTP API — with number portability (MNP), short-code handling and clustering built in? ySMSC, part of yREMORA’s family of telecom infrastructure, delivers the complete SMSC solution for mobile network operators (MNOs), MVNOs and messaging providers — on commodity Linux servers, without proprietary hardware or per-TPS license meters.
Every operator’s messaging setup is a little different: different aggregators, different HLR quirks, different national portability systems, different short-number services generating revenue in the background. Most SMSC vendors sell a rigid box and expect your network to bend around it. ySMSC does the opposite — the full feature set comes standard, and where your network does something unique, we build custom implementations to match it.
SMPP, SS7/MAP and HTTP API: every SMS interface, submit and receive
ySMSC speaks all three languages of modern SMS messaging, in both directions:
- SMPP SMSC connectivity — for A2P aggregators, ESMEs and application clients, submit and receive.
- SS7 / MAP over SIGTRAN — MO and MT SMS toward your MSCs and HLR, including SRI-SM home routing so terminating traffic stays under your control, plus ATI helpers and alertServiceCentre-driven retries.
- SMS HTTP API — a clean JSON-over-HTTP(S) interface to submit and receive messages, ideal for in-house platforms, customer portals and enterprise integrations.
Store-and-forward scheduling runs on a robust MariaDB/MySQL queue, so no message is lost between submission and a delivered handset.
Short code SMS handling and parking-service integrations
Short codes are where much of today’s SMS revenue lives — parking payments, voting, donations, info services, premium content. ySMSC handles short-number traffic natively and integrates directly with parking and other short-number service platforms, so you can route, charge and report on shortcode traffic without bolting on a separate gateway.
Number portability (MNP): SQLite or country-customized MySQL
Ported numbers break naive routing, and every country’s MNP regime is different. ySMSC offers two number-portability database options:
- SQLite NPDB — a simple, general-purpose local portability database for straightforward deployments.
- MySQL NPDB, customized per country — tailored to your national MNO portability system, with the lookup logic, data feeds and normalization rules your regulator’s scheme requires.
Home and treaty-area country codes are configurable, and MNP lookups feed routing decisions with proper national-format normalization — so ported numbers land correctly the first time.
Scalable SMSC clustering: smsc1, smsc2 … smscX
ySMSC is horizontally scalable: start on a single commodity server and grow into a cluster as traffic demands. Two clustering models are available:
- DB-plane (Galera): nodes share state through a MariaDB Galera multi-master cluster.
- Application-plane: each node runs its own database, with SMSC writes replayed peer-to-peer.
Choose the model that matches your data-center topology. Either way, you add capacity by adding nodes — not by renegotiating a license.
Control and configuration via HTTP API
The entire platform is driven by HTTP API requests for both control and configuration. Provision accounts, adjust routing, manage cluster peers and monitor operations from your orchestrator or OSS — the API and the CLI drive the same machinery underneath. Operator-made configuration overrides live in dedicated files that survive every upgrade untouched.
Real-time charging integrates over RADIUS (authorization and CDR accounting toward your OCS), with a JSON/HTTP charging bridge available for modern backends.
Custom SMSC implementations for your network
Beyond the standard feature set, the yREMORA engineering team develops custom implementations on top of ySMSC: bespoke routing logic, country-specific MNP integrations, connections to local short-number and parking platforms, tailored charging flows and interconnect-specific behavior. You get a product, not a project — with the engineering capability right there when your network needs something specific.
Frequently asked questions
What is ySMSC?
ySMSC is carrier-grade SMSC (Short Message Service Center) software. It handles MO/MT SMS over SMPP, SS7/MAP and HTTP, with store-and-forward, number portability, short-code support, clustering and a full HTTP control API.
Which protocols does ySMSC support?
SMPP (submit and receive), SS7/MAP over SIGTRAN (including SRI-SM home routing and ATI), and a JSON-over-HTTP(S) API for message submission, reception, control and configuration.
Does ySMSC support number portability (MNP)?
Yes. Choose a simple SQLite NPDB for general deployments, or a MySQL NPDB customized to your country’s MNO portability system.
Can ySMSC scale horizontally?
Yes. Run a single node or a cluster (smsc1, smsc2 … smscX) using either MariaDB Galera DB-plane clustering or application-plane peer-to-peer replication.
Who is ySMSC for?
Mobile network operators (MNOs), MVNOs, and SMS/messaging service providers replacing legacy SMSC platforms or bringing messaging in-house.
