🟢search_esims(country, days, data_gb, unlimited, countries, ...)
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.
