Use eSIM Grab in Grok
Turn your AI into your personal eSIM search engine. Connect once, then compare current plans for one country or a multi-country trip.

Read-only tools. No eSIM Grab account, API key or sign-in required.

Use it on your phone
Grok documents connector support on web, iOS and Android. Add a custom MCP connector in an eligible account; managed teams may need an administrator.
Connect eSIM Grab
- Open grok.com/connectors and choose New Connector → Custom. On a managed Business or Enterprise team, an administrator may need to add the connector first.
- Name it eSIM Grab and enter the server URL above. Review the connection settings. This public server needs no eSIM Grab credentials; if the client requires unsupported authentication, report that instead of inventing credentials.
- Enable the connector in a new conversation and run the test request below. Verify a real MCP tool result before reporting a successful connection.
Workspace policies may restrict custom connections. Reuse an existing connection when available. A custom connection is separate from a public directory listing.
Verify with a live search
Use eSIM Grab to compare Japan eSIM plans with at least 10 GB and 7 days of validity in USD. Show current prices, restrictions and source links. Tell me which tools you used.
The agent should resolve Japan, search current plans and report the returned result. Only call the connection ready after a real MCP tool call succeeds. A saved URL or web browsing alone does not verify MCP access. Empty results are valid; never invent an offer.

I will spend 7 days in Japan, then 3 days in South Korea. I need 5 GB in Japan and 2 GB in South Korea. Compare one plan for the whole trip with separate purchases in USD, and explain coverage, validity and data limits.
MCP exposes current catalog offers only. Historical prices remain proprietary. Tools cannot buy or activate an eSIM. eSIM Grab may earn a commission at no extra cost to you.
