What it can do

Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.

  • search_destinations

    Countries and regions with eSIM plans, with the lowest price per currency. Leave query empty to list all.

  • list_plans

    Plans that work in a country or region, cheapest first, with optional filters for data, days and price.

  • get_plan

    One plan with prices and every country and mobile network it covers.

  • recommend_plans

    Plans for a trip to one or more countries: estimates the data needed from the days and how the user uses their phone, then suggests the best-value plans that cover every country for the whole trip.

  • compare_plans

    Side-by-side comparison of 2 to 5 plans: data, days, price per GB and per day, countries and hotspot.

  • country_networks

    The mobile networks GLOBALCELL eSIMs use in a country, how many plans work there and the lowest price.

  • check_device

    Whether a phone, tablet or watch model supports eSIM, from a list of known models, with how to check on the device itself.

  • create_order

  • check_usage

    Data used and left on the eSIM of a fulfilled order, per package, with start and expiry dates.

  • diagnose_esim

  • install_help

    Step-by-step eSIM installation and first-use help for iPhone or Android, and fixes for common problems.

Common questions

Is GLOBALCELL eSIM safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.1.0) reached the registry 11 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
