• search_esims read-only

  Search the travel eSIM catalog of esimoa (이심모아) and compare plans for a destination. Filter by trip length, data, unlimited or daily data, local phone number, local or roaming network, multi-country coverage, price, provider, hotspot and 5G. Sort by "recommended" (esimoa’s default order), "price" (lowest first), "data" (most data first), "price_per_gb" or "validity" (longest first). Each result includes its `id` (for get_esim and compare_esims) and a `url` to the plan page on esimoa.com. Prices are in KRW.

  Parameters:

  • days — integer — Trip length in days. Plans covering at least this many days (and not much longer) are returned.
  • lang — string — Language for country names and the plan page. Match the user’s language (ko, en, ja, zh-CN, zh-TW, es, fr, ar, vi, th, id, it, de).
  • sort — string — recommended | price | data | price_per_gb | validity
  • limit — integer — Number of plans (default 5, max 10).
  • five_g — boolean — true = 5G network. Checked within the top 50 matches, so the total is approximate.
  • country — string — Destination country — ISO code (JP) or name in any language (Japan, 일본).
  • data_gb — number — Minimum data needed in GB.
  • hotspot — boolean — true = hotspot/tethering supported. Checked within the top 50 matches, so the total is approximate.
  • network — string — local = local carrier network (usually faster); roaming = roaming network.
  • provider — string — Provider code exactly as returned in results (e.g. from a previous search).
  • countries — array — Multi-country trip — only plans that work in ALL of these countries (ISO codes or names). Use instead of country.
  • data_type — string — daily = data allowance resets every day; total = one allowance for the whole trip.
  • unlimited — boolean — Only unlimited-data plans.
  • max_data_gb — number — Maximum data in GB.
  • local_number — boolean — true = only plans that include a local phone number for calls/SMS.
  • max_price_krw — integer — Maximum price in KRW (budget).
  • min_price_krw — integer — Minimum price in KRW.
  • multi_country — boolean — true = multi-country (regional) plans only; false = single-country plans only.
