The math behind Skyhigh Mobile.

A US consumer MVNO modeller built for Sumitomo. Every assumption is editable — net subscriber adds per year, plan mix and retail prices, per-plan network fees, CAC, and the Reach platform license fee. Watch the 5-year P&L, dashboards, and break-even year update in real time. The economics here are network-agnostic: the model is driven by gross margin per plan, so the commercial math holds regardless of the underlying carrier arrangement Sumitomo selects.
