New: do it all inside your AI

Add MeiSIM to ChatGPT, Claude, or Grok and get any of these just by asking: a travel eSIM, a real US phone number, or a top-up. With an API key, your agent also reads and sends texts on its own numbers. The assistant searches, takes the payment, and delivers, right in the chat.

Add the connector

Paste the MeiSIM URL into your AI's connector settings once, or run one command in your IDE.

Just ask

"5GB for Italy," "get me a US number," or "read the last text on my number." It finds the right option and price.

Pay & get it

Pay on a secure Stripe page. Your eSIM QR or US number arrives in the chat or by email.

Add MeiSIM to your assistant

Works anywhere that supports the open Model Context Protocol.
