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
