With Pay as you go, your unlocked iPhone arrives ready to use straight out of the box. There’s no contract, so there's no commitment and you don't need a credit check. That means you’re free to change carrier and you only pay for what you use.
Pay as you go starter packs are available at the Apple Online Store, pre-loaded with call minutes or credit, texts and data. Once your starter pack runs out, simply top up again. Carriers offer a variety of top-up options and added benefits. Visit your carrier website for details.
