How to Choose Where to Buy

The lowest advertised price is not always the best deal. Compare trade-in value, carrier requirements, installment terms, bill credits, and upgrade restrictions before choosing where to buy.

Latest iPhone Duo Buying Updates

We are tracking Apple, major U.S. carriers, and retailers as preorder and launch offers are published and verify their terms.

  1. AppleApple’s carrier-offer details distinguish Duo eligibility by carrierApple shows eligible iPhone Duo offers of up to $1,200 with AT&T and up to $1,000 with T-Mobile at Apple, each subject to its own trade-in terms. Apple’s detailed eligibility list does not include iPhone Duo in the displayed Verizon offer, so the generic Verizon banner is not counted as a confirmed Duo deal.
  2. T-MobileT-Mobile publishes a direct Duo offer without trade-inT-Mobile advertises up to $1,000 off with a new line, port-in, and an Experience Beyond plan, using up to 36 monthly bill credits. No trade-in is required. This direct T-Mobile offer is separate from Apple’s T-Mobile-at-Apple trade-in offer.
  3. VerizonVerizon publishes Duo switcher bundles and standard payment termsVerizon’s launch announcement describes a $72/month Simplicity switcher bundle for 48 months and a separate Apple Watch or iPad line bundle with up to $600 in credits over 36 months. Verizon’s direct product page lists 12-, 24-, 36-, and 48-month device-payment terms. These bundles do not confirm a phone-only device discount or consumer trade-in offer.
  4. Best BuyBest Buy lists Duo carrier trade-in offers for AT&T and VerizonBest Buy’s AT&T offer page advertises up to $1,200 with qualifying trade-in and plan terms. Its Verizon offer page advertises up to $1,000 for add-a-line or $840 for an upgrade on selected MyPlan options. The three checked SKUs remain Coming Soon; Verizon’s current price display is malformed and no monthly payment is inferred.
