If you’re an Xfinity Mobile Plus member looking to upgrade, Xfinity has a strong set of phone deals running through October 8, 2026. The headline offer is the iPhone 18 Pro Max on us with a qualifying trade-in, but there are also significant discounts on other iPhones, Google Pixel phones, and Motorola devices, including a $400 no-trade-in-required option across all three brands. Deal score: +42.

Note that Xfinity Mobile requires an active Xfinity Internet subscription. All discounts are applied as monthly bill credits over a 36-month device payment plan. Taxes and fees are extra, and eligibility and trade-in values vary by device.

What to Know Before You Switch

• Your trade-in device matters a lot. The top credits go to recent iPhones, with iPhone 15 Pro or newer generally qualifying for the highest trade-in values. Older devices get significantly less, so check your trade-in estimate before assuming the headline number applies to you.
• You’ll need the top-tier Mobile Plus Unlimited plan. Flagship phone deals like the iPhone 18 Pro Max promo are tied to the highest plan tier. Lower-tier plans typically don’t qualify for the best offers.
• This promotion cannot be stacked with first-year-free plan offers or other discounts. If you’re eyeing a first-year-free Mobile Select deal, know that combining it with the phone promotion can cancel the plan. A new line activation is also required within 30 days.
