The order is the rubric on the research method page, not a price sort. Nomad and Airalo sold at least one plan for less here on 30 Oct 2026, and the Cheaper plans column names each one with both prices. Not published means no price for Australia was read for that provider. No coverage means the provider does not sell that destination. No cell is filled with an estimate.
Every plan in this index is data only, with no local phone number. All of them need an eSIM-capable handset, which means iPhone XR or newer and most Android phones from 2020.
