Search prepaid travel eSIM data plans for a destination — the SIM card / mobile data / roaming option for a trip. Use this first for any "data plan for my trip to X" request. Includes unlimited plans where the traveller picks the number of days, and fixed-data plans. Filter by unlimited vs fixed-data, minimum data, and validity. Unlimited plans are quoted per day, fixed-data plans as a one-off total — never compare those two numbers directly. The unlimited total is the per-day price × days, with a volume discount from 7 days, so pass days (trip length) to get that total quoted alongside the daily rate. Price differences between similar plans come from the routing IP country (routing_ip_country) and the supported networks (speed) — quote both when comparing plans. Results are grouped: fixed-data plans first, then unlimited; each group sorted by price. Returns variant_id values to pass to create_checkout.
