Alt eSIM vs Holafly
Holafly is the Spanish unlimited-data leader, with Fair Usage Policy (90GB/week) and premium pricing (~US$27 for Japan 5 days). Alt eSIM uses daily high-speed allowances (e.g. 1GB/day, then throttled unlimited) at 70%+ cheaper — light users save a lot; heavy users may justify Holafly's premium.
