Common questions

Is Cheapest eSIM Korea (최저가e심) safe?

It passed 1 of 1 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 (1.0.0) reached the registry 22 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 in developer mode.

What can I use instead?

How the data is made

Every day at 20:00 KST, option-level prices of travel eSIM/SIM products on Naver SmartStore are collected from each seller's product API.
Only data that passes automatic verification (live re-check of a sample, integrity checks, screen-text audit) is published; failed runs keep the previous day's data.
Unlimited lists include only data-only, no-throttling options; call plans, slow-after-cap, 1+1 bundles and sold-out options are excluded. SIM prices include shipping.
"Cheapest" (pagePrice) follows the same rule as the website: sellers with ≥1,000 reviews (filled up to 5 sellers by review count when fewer), bundles excluded, the cheapest single option per seller.
No recommendation scores and no paid placement: sellers are ordered by review count.

Limits

120 requests/min per IP for the API, 300/min for MCP. For bulk use, download the daily CSV: https://pyungyo.com/esim/data/esim-price-trends.csv
