1NCE is a Cologne-headquartered global IoT connectivity provider best known for the IoT Lifetime Flat — a single one-time fee that bundles a multi-network SIM with 500 MB of data and 250 SMS over a 10-year subscription. The 1NCE Management API on api.1nce.com/management-api exposes the same surface as the customer portal across six product areas — Authorization, SIM Management (v1 and v2), Order Management, Product Information, Support Management, and 1NCE OS — with OAuth 2.0 bearer-token security and a public api-catalog document. 1NCE OS layers integration, device locator, inspector, optimizer, and partner-plugin services on top of the connectivity bundle, while the company's GitHub organization publishes the 1NCE IoT C SDK, FreeRTOS / Zephyr / Arduino blueprints, AWS IoT onboarding tooling, CloudFormation templates, and an MCP server for AI agent integration.
