In short: Airalo is the biggest travel-eSIM provider: you buy data packs per country or region, with no number; minutes and texts come only in individual packs, not as a flat rate. Simsalasim is a full phone plan as an eSIM with a German number, unlimited data in 100 countries, and calls, for €10 a month.
