What can you do with sinoconnection esim mcp?

SinoConnection eSIM — MCP Server

The China & Asia travel eSIM specialist — with global coverage in 200+ countries.

A public, read-only Model Context Protocol server that lets AI assistants (ChatGPT, Claude, Gemini, …) search travel-eSIM plans, look up plan details, and check device eSIM compatibility on a user's behalf. Specialized China plans deliver uncensored internet without a VPN.

Operated by SinoConnection 华人通 (SinoConnection LLC), a physical wireless store in Elmhurst, Queens NY, serving the community since 2001.

Tools

Tool	Purpose
`search_esim_plans`	Search plans by country / region / type / duration. Returns `price_usd` (what the customer pays, current discount already applied), data, validity, fair-usage caveats, and `china_open_internet`.
`get_plan_details`	Full details for one plan by id.
`check_device_compatibility`	Check whether a phone/tablet supports eSIM.
`create_checkout_link`	Get a secure checkout URL for a plan; the customer completes payment on-site.

Purchasing is completed by the human on sinoconnection.com — the connector never handles payment.

Privacy

Read-only. No account, no sign-in; the connector does not collect name, email, phone, or payment details. See the Privacy Policy (§ AI Assistant Connector).

About the "no-VPN in China" note

Per Airalo's official documentation, China, Regional Asia, and Global eSIMs with China coverage work in China without a VPN (international routing bypasses the Great Firewall). The china_open_internet field marks plans that cover China.
