Siima

Siima for AI agents

AI assistants can search Siima's travel eSIM catalogue and complete purchases for their users through our Model Context Protocol (MCP) server. The agent finds the right plan, hands the user a secure Stripe checkout link, and the eSIM — QR code, one-tap activation link, and manual codes — arrives in the buyer's email within a minute of payment. No account or signup required.
