AT&T offers the newly-released Apple iPhone 18 Pro from $0 per month via up to $1,200 in bill credits over 36 months with an eligible trade-in and eligible plan. Shipping is free. The maximum $1,200 credit requires activation on an AT&T Premium 2.0 plan or higher and a qualifying trade-in with a minimum value of $180; an iPhone 14 or higher, excluding the iPhone 16e, is accepted in any condition. New and existing customers can qualify when activating a new line or upgrading an existing line, and the phone must be purchased on a 36-month installment plan. Credits begin within three bills, and credits may stop if service is canceled or the device is paid off or upgraded early. Shop Now at AT&T Mobility
