AT&T offers trade-in toward new iPhone 15 purchases — credit varies by your old phone's condition and any active promo. Higher storage tiers typically receive proportionally larger credits.
The verdict, & two little voices
Should you actually get the 128 GB Apple iPhone 15 on AT&T?
The editor weighs in — flanked by the optimist on her shoulder and the cynic on the other.
“USB-C, 2000 nits, 48 MP camera, and Dynamic Island at $385 is the biggest standard iPhone upgrade in years.”
“Apple shipped 60 Hz again in 2023 - Android phones at half the price have offered 120 Hz for two years.”
