"iPhone 15: Carrier Offers, Global Launch, and Standout Features"

T-Mobile and Verizon are offering up to $1,000 off the new iPhone 15, but the deals require switching to their pricier plans. AT&T offers the easiest deal, requiring users to be on a variety of its unlimited plans and trade in a recent phone. Verizon's deal requires adding a new line or switching from a rival provider and signing up for its priciest unlimited plan. T-Mobile's best deal is available to users on specific plans and requires trading in an eligible device. All three carriers also offer lesser deals for older devices or those who don't want to switch plans.
