How we work out the true monthly cost
We add the phone's price to everything you'd pay for the SIM plan over 24 months: any introductory price, the price after it, and any yearly rise the network has published for contracts. Then we divide by 24. Rolling plans are counted at today's price for all 24 months, because the network can change it. Nothing here is a guess: if a price is more than 48 hours old, we don't show it. See how we rank.
