What separates plans of equal length
Every plan in the table lasts 30 days, so length is not a tiebreaker. Check two things instead: how you add data, and what happens to an unused plan.
A plan you can top up saves you from buying a second eSIM mid-trip. A clear refund rule protects you if travel plans change.
