About

Seamless OS is a cloud-native BSS/OSS telecom platform from Telness Tech that eliminates traditional telecom complexity by combining core billing, customer operations, service activation, and network-agnostic management into a single, fully automated stack designed for fast, digital-first mobile service delivery. It enables companies to launch their own branded mobile operators by supporting prepaid and postpaid plans, eSIM and travel eSIM products, mobile apps, checkout and payments, regulatory billing and taxation, and complete subscriber lifecycle management with modular APIs and webhook integrations. Built-in AI and agentic capabilities automate workflows, customer support, and operational tasks to reduce overhead and future-proof services for the AI era, while the platform’s flexible, modular architecture lets operators configure, bundle, and upsell products such as data packs, devices, and value-added services.
