Visit esimfly.net →DocsPricing
eSIMfly's eSIM API lets companies buy, provision, and manage eSIMs programmatically at wholesale rates. It provides a package catalog with wholesale pricing, order creation and top-ups returning QR codes and activation details, eSIM lifecycle management (status, usage, activate/suspend/cancel, network events, SMS), and webhook notifications for lifecycle events. Requests are authenticated with HMAC-SHA256 signatures over timestamp, request ID, access code, and body. Coverage spans 200 countries and 450+ networks with local, regional, and global plans. Billing is balance-based; rate limit is 1,000 requests per hour per account. Official Node.js/TypeScript SDK (@esimfly/sdk, MIT-licensed, zero dependencies, Node.js 18+) and an MCP server (hosted at mcp.esimfly.net/mcp or via @esimfly/mcp) are available. Target users include travel apps, resellers, MVNOs, IoT/fleet platforms, and superapps.
