Nothing serious here today

Today is the operative word: we check SimAbroad eSIM every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

buy

get_buy_link

Get a simabroad.com checkout link for one eSIM plan, by the id returned from search_esim_plans. Opening the link adds that exact plan to the cart and opens checkout; the traveler pays there (card, Apple Pay or Google Pay) and gets the eSIM QR code by email. Nothing is charged by calling this tool.

destinations

list_destinations

List countries and regions where SimAbroad sells eSIM plans right now, with the country_code to pass to search_esim_plans. Search accepts names, common aliases ('USA', 'UK') and codes. Countries marked multi_country_only are covered by regional or global plans only.

esim

search_esim_plans

Search SimAbroad eSIM plans for a trip. Pass country_code (ISO 2-letter, e.g. 'JP', or a code from list_destinations such as 'USPR') to get every plan that works there: single-country plans plus regional and global plans that cover it (see the coverage field). Or pass region for multi-country plans. Use min_validity_days with the trip length and min_data_gb or unlimited to match the traveler's needs. Returns only plans on sale now, cheapest first, with the USD price charged at checkout and a buy_url that opens checkout for that exact plan.

SimAbroad eSIM — questions

Answers built from our own checks of this server.

What can SimAbroad eSIM do?

It exposes 3 tools, read directly from the server on our last check. Among them: get_buy_link, list_destinations, search_esim_plans. 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 SimAbroad eSIM working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 1351 ms. The bar chart above shows every period we have measured.

How do I connect SimAbroad 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.

Does SimAbroad eSIM need an API key?

No. SimAbroad eSIM completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is SimAbroad eSIM?

It answers our handshake in 1351 ms on average, which is faster than 2% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
