No — iPhone 15 Pro Max doesn't support expandable storage, and Apple/Samsung don't offer post-purchase storage upgrades. Pick the tier that fits your two-year plan.

Does XFINITY Mobile offer trade-in credit for the iPhone 15 Pro Max 256 GB?

XFINITY Mobile offers trade-in toward new iPhone 15 Pro Max 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 256 GB Apple iPhone 15 Pro Max on XFINITY Mobile?

The editor weighs in — flanked by the optimist on her shoulder and the cynic on the other.

The 5x telephoto and 4441 mAh battery make the 15 Pro Max worth $100 more than the Pro - the zoom reach alone justifies it for photography-focused buyers.

“The 5x tetraprism telephoto is the most useful iPhone optical upgrade in years - distance photography is transformed.”

“Apple locked the headline camera feature to the expensive model - the standard Pro got nothing new in zoom.”
