Multiple integration paths
Use TCP/XML for low-latency bidirectional links, HTTP MO for callback-style apps, and HTTP MT to originate sessions toward subscribers.
SigWay is a USSD gateway that connects M3UA/SS7 networks to your services through TCP/XML, HTTP MO, and HTTP MT—built for carriers, integrators, and high-scale USSD deployments. An SMS gateway is on the same product line and coming soon.
Whether sessions start in the network or in your app, SigWay routes USSD traffic, manages dialogs, and exposes clean integration surfaces your teams already know how to operate.
Use TCP/XML for low-latency bidirectional links, HTTP MO for callback-style apps, and HTTP MT to originate sessions toward subscribers.
Automatic dialog allocation for SS7-initiated traffic, explicit ranges for app-initiated flows, and consistent IDs end to end.
Per-MSISDN rate limiting, shortcode filtering, and keep-alive ping/pong so production behavior stays predictable under load.
Full USSD session lifecycle (begin, continue, end, abort) with GSM7 and UCS2 handling where your applications need them.
Production-ready SS7/M3UA to application bridging: TCP/XML, HTTP MO and MT, session management, ATI, rate limits, and shortcode routing—documented and licensable today.
Extend the same SS7-side footprint with a dedicated SMS path for mobile-terminated and mobile-originated messaging—aligned with how you already operate SigWay. Technical details, interfaces, and pricing will be published at launch.
SigWay sits between your SS7 stack and application tier—one gateway, several ways to integrate. A dedicated SigWay SMS Gateway is planned on the same product line (see Roadmap). For a companion USSD menu platform built on SigWay, see Menu Builder below.
These operators rely on SigWay for production USSD signaling.
The full SigWay USSD Gateway API reference covers interfaces, message types, procedures, and examples. It ships as a single HTML page you can browse offline or host beside your deployment.
Includes overview, TCP/XML framing, HTTP MO/MT, SS7- and app-initiated sessions, ATI, and protocol details.
SigWay USSD Gateway and USSD Menu Builder are priced for flexibility: buy the gateway alone, add Menu Builder when you are ready, or take a full-stack bundle on better terms. Menu Builder is licensed for use with SigWay (it is not sold as a standalone product for other gateways). SigWay SMS Gateway pricing will be announced when it ships. Figures below are indicative—volume, pilots, bundles, and multi-year terms are worked out on quote.

Talk to salesMenu Builder is priced per SigWay gateway instance you pair it with (typical: one Menu Builder deployment alongside one licensed gateway server). Bundle pricing rewards buying both together; add-on pricing applies if you already run SigWay.
~USD 2,000
One-time license per paired gateway instance
Annual support (indicative): +USD 120 per paired server (on top of gateway support)
Quote add-on~USD 5,100
SigWay gateway + Menu Builder, one-time per stack
Annual support (indicative): ~USD 400 per stack (gateway + Menu Builder), vs USD 420 à la carte

Same flexibility as gateway-only pools

Discuss optionsAll amounts are indicative. Taxes, export, deployment scope, acceptance testing, and SLAs are confirmed in writing. Gateway pool discounts still apply to gateway license lines only unless otherwise agreed for a combined pool. Menu Builder support is quoted with each deployment; bundled support is a target bundle—not a guarantee until contracted.
