Captured live from the server via tools/list.

search_esim_plans

Search travel eSIM plans for any of 200+ countries. Specialized China plans deliver uncensored internet WITHOUT a VPN (unlike most eSIMs, which are throttled or blocked in China) — only when the plan's china_open_internet field is true. Also covers regional Asia and worldwide bundles. Quote `price_usd` — that is the price the customer pays in USD, with any current sitewide discount already applied; `list_price_usd` is the original and `on_sale`/`discount_pct` show the saving. If is_fair_usage_policy is true, the plan is NOT truly unlimited — relay the cap.

      "description": "Exact validity in days (optional filter)"
    }
  }
}

get_plan_details

Full details for a specific eSIM plan by id: coverage, data, validity, networks, activation window, and any fair-usage limits. Use before creating a checkout link.

Parameters1

string

required

Package id from search_esim_plans

Raw schema

{
  "type": "object",
  "properties": {
    "id": {
      "type": "string",
      "description": "Package id from search_esim_plans"
    }
  },
  "required": [
    "id"
  ]
}

check_device_compatibility

Check whether a phone/tablet model supports eSIM before recommending a plan. Free-text device name in; compatible yes/no plus closest matches out. IMPORTANT: eSIM hardware support is only HALF the requirement — the phone must ALSO be carrier-unlocked. This tool returns an unlock_required flag + how to verify; always relay it, because a locked phone cannot use a travel eSIM.

Parameters1

device

string

required

e.g. "iPhone 14 Pro", "Galaxy S24"

Raw schema

{
  "type": "object",
  "properties": {
    "device": {
      "type": "string",
      "description": "e.g. \"iPhone 14 Pro\", \"Galaxy S24\""
    }
  },
  "required": [
    "device"
  ]
}

create_checkout_link

Create a secure checkout link for a chosen plan (by id). Before sharing the link, confirm with the customer that their phone is (1) eSIM-compatible AND (2) carrier-unlocked — a locked phone cannot use a travel eSIM. The customer completes payment themselves on SinoConnection's checkout page (sign-in required) — you never handle card details. Returns a URL, the plan title, and price_usd (current discount already applied).

Parameters1

string

required

Package id from search_esim_plans

Raw schema

{
  "type": "object",
  "properties": {
    "id": {
      "type": "string",
      "description": "Package id from search_esim_plans"
    }
  },
  "required": [
    "id"
  ]
}

get_help

Answer customer support and policy questions about SinoConnection eSIMs: the REFUND POLICY, how to INSTALL (with step-by-step videos), activation, and how to get support. Call this whenever the customer asks about refunds, cancellations, installation/setup, activation, or help — do NOT answer these from memory; relay this authoritative content.

Parameters

No parameters.

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.

Connect

Endpoint: https://70ug3hqb29.execute-api.us-east-1.amazonaws.com/mcp
Transport: Streamable HTTP (MCP JSON-RPC 2.0)
Auth: none (public, read-only)

ChatGPT / other MCP clients

Add a remote MCP server pointing at the endpoint above.

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.
