search_esim_plans — Search travel eSIM plans
Find the cheapest travel eSIM data plans for a destination from 21 providers (Airalo, Holafly, Nomad eSIM, Saily, Ubigi, Yesim and more), filtered to what a trip needs. Returns plans sorted by price (cheapest first) with data allowance, validity, price, price per GB, local network, speed policy, the date the price was checked, a page on eSIMCompare that cites the source, and a buy link. Buy links marked affiliate_link may earn eSIMCompare a commission; the price is the provider's own either way, and where a buy link applies a reader discount the plan also gives price_through_buy_url_usd.

}esim_price_index — Travel eSIM price index
What a week of mobile data costs a traveler: the cheapest eSIM with at least 5 GB valid for at least 7 days, per country, from eSIMCompare's price index of 194 countries. With a country: its price, the plan behind it, the cheapest price per GB, the cheapest unlimited week and its rank among all countries. Without one: the median, the cheapest and dearest countries, and which providers are cheapest most often.
