Shangtong Technology (Jiangxi Shangtong Technology Development Co., Ltd.) was founded in 2009. Its official positioning is as a domestic enterprise unified communications service provider in China. Core products include a SaaS cloud call center, 400 business hotline, PaaS enterprise SMS, number verification, and virtual number/middle-number services. Its offering is more focused on Chinese enterprise customer service, marketing support, and notification delivery scenarios, rather than being a standalone email or international messaging platform.
In terms of channels, Shangtong covers two main categories: SMS and voice. On the SMS side, it provides trigger-based SMS/MMS services for identity verification, reminders and notifications, information confirmation, and similar use cases. The platform is said to be compatible with carrier and third-party SMS interfaces, using security filtering and channel selection to improve delivery stability. On the voice side, the focus is on 400 phone numbers and cloud call centers, with support for inbound and outbound call management, intelligent routing, multi-line calling, web calling, smart screen pop-ups, and integrations with CRM, ticketing systems, knowledge bases, and data analytics. AI capabilities include AI voice bot answering, outbound calling, intelligent IVR, and online customer service.
The official website does not publish SMS unit prices, 400 number fees, agent seat fees, or API call pricing. Its onboarding process only mentions “selecting a number, choosing a package, configuring features” and “contract signing and payment.” Before procurement, buyers therefore need to confirm plans, number availability, feature editions, SMS volume tiers, and after-sales terms with sales. On the API side, the main content only states that the enterprise SMS platform is compatible with carrier and third-party SMS interfaces. Public documentation, SDKs, Webhooks, or console descriptions were not found, so there is limited information available for technical evaluation.
Compliance is one of its relatively prominent selling points. Applying for a 400 phone number requires enterprises to provide business licenses and other real-name qualification documents, with the process emphasizing “two certificates and one invoice” and real-name network access. The company also discloses that it holds a cross-regional value-added telecommunications business license, ISO27001/BS7799 information security management system certification, and other credentials. In terms of performance, the website uses phrases such as “timely, stable, accurate, and compliant,” and mentions 50+ carrier deployments and 500+ service cities. However, it does not provide specific SMS delivery rates, latency figures, SLA terms, concurrency limits, or outage compensation standards.
The main advantage is its product coverage across voice customer service and enterprise SMS, making it suitable for domestic 400 hotlines, customer service centers, notification SMS, number verification, and virtual number/middle-number scenarios. It also describes its scale as nearly 800,000 customers and support for 3,000+ well-known enterprises. The downside is limited transparency around pricing, APIs, delivery rates, and service SLAs, so it is not ideal for developer teams that want to quickly self-serve an integration based only on public documentation. It is better suited to China-based enterprises with a formal procurement process that need an integrated 400 phone and customer service system.
As a mainland China vendor, its official website has complete ICP filing information and is usually directly accessible from within China. Payment methods are not disclosed; the site only indicates contract signing and payment. If you only need a standardized SMS API, it is also worth comparing alternatives such as Alibaba Cloud SMS, Tencent Cloud SMS, Huawei Cloud Message & SMS, Ronglian Cloud, and Montnets.
