This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

This server publishes 1 more address. The block above uses the one we reach during checks; the full list is under Endpoints below, and the author may intend a particular one for your client.

Available tools 12

order
check_order
Order status. Once "fulfilled", a new eSIM includes its install links, QR code link and manual codes.

GLOBALCELL eSIM — questions

Answers built from our own checks of this server.

What can GLOBALCELL eSIM do?
It exposes 12 tools, read directly from the server on our last check. Among them: check_device, check_order, check_usage, compare_plans, country_networks, create_order and 6 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is GLOBALCELL eSIM working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 182 of 182 checks got a reply (100.0%), average response time 178 ms. The bar chart above shows every period we have measured.
How do I connect GLOBALCELL eSIM?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to GLOBALCELL eSIM?
No API key is involved. GLOBALCELL eSIM answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is GLOBALCELL eSIM?
It answers our handshake in 178 ms on average, which is faster than 76% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
