How we worked it out

The same phone. iPhone 18 Pro Max, 256GB, at every network.
Unlimited data with no speed cap, because ours has none. Each network is matched on its cheapest unlimited plan without one.
Two years, all in. The whole phone paid off, plus two years of data. A network that sells the phone over 36 or 48 months has the phone counted once, at its full price.
Price rises counted for every network, at the amounts each one publishes.
Read on one day from each network’s own website, 2 October 2026. Prices change, so check the network’s site before you decide.
