How Apple's iPhone 18 price increases impact your trade-in value at Verizon, T-Mobile, or AT&T

Wall Street thinks sales of the pricier new Apple (AAPL) iPhone 18 lineup are off to a brisk start. That's good news from an economic standpoint because it's not cheap to buy one in-store, despite stepped-up carrier promotions. US wireless carriers Verizon (VZ), T-Mobile (TMUS), and AT&T (T) have increased incentives for iPhone purchases, according to analysis by Bank of America's Michael Funk. The maximum trade-in credits for the iPhone 18 Pro Max increased to $1,200, up from $1,100 for the iPhone 17 Pro Max and $1,000 for the iPhone 16 Pro Max. The trade-in credit for the iPhone 18 Pro is also $1,200. But that's where the savings end.
