Decide whether you want instant credit toward a new device or the highest possible cash payout, since those are two different paths with different winners. For guaranteed credit with the least hassle, Apple Trade In, Amazon Trade-In, or your carrier’s trade-in program are the current standard options. For the highest cash payout on a phone in good condition, a peer marketplace like Swappa in the US typically beats instant trade-in credit, at the cost of more effort listing it yourself.
Trade-in credit: the low-effort path

Apple Trade In. Trade online or in an Apple Store. Online, you return your old device within 14 days of receiving the new one, Apple inspects it over 3 to 5 business days, and credit lands as an Apple Gift Card or against your purchase. In-store, evaluation and credit happen on the spot.
Amazon Trade-In. Mail in using a free shipping label, with 45 days to send the device, or drop it at a participating location. Payout comes as a digital Amazon Gift Card, and some devices qualify for instant payment.
US carriers. Verizon issues instant credit, account credit, or a gift card after a mail-in trade, though non-Verizon customers need to add a line first. AT&T typically pays out as bill credits spread across a 30-month installment term rather than a lump sum. T-Mobile gives instant credit for in-store trades, or a one-time bill credit within about two billing cycles for mail-in.
UK carriers. Vodafone’s Trade-in Tool gives a guaranteed value code redeemable in-store or by mail through DPD, processed within about 5 working days of the device arriving. EE’s Recycle and Reward program is open to non-EE customers too and pays via PayPal or bank transfer.
Selling for cash: more effort, usually more money
If your phone is in good condition and you’re willing to list it yourself, a peer marketplace generally pays more than trade-in credit does. Swappa is the reputable option in the US. Cashify serves the same role in India. Listing takes more work, clear photos from multiple angles, an honest condition description, and some back-and-forth with a buyer, but you’re not accepting a carrier’s instant-credit discount in exchange for convenience.
What actually changes the price, regardless of where you sell
The phone’s model and generation matter most, an older or less desirable model earns proportionally less no matter the platform. Condition is the second-biggest factor: a case and screen protector used throughout the phone’s life pays off here, since scratches and dents reduce value more than most sellers expect. Keeping the original box and charger, while not essential, makes a listing more appealing.
Before sending or handing over any device: back up your data, sign out of every account, remove the SIM and any SD card, and perform a full factory reset. A phone still logged into iCloud or a Google account with Activation Lock enabled is close to worthless to a buyer, since they can’t set it up as their own.
Frequently asked questions
Is trade-in credit or selling for cash worth more? Selling for cash on a marketplace like Swappa usually pays more for a phone in good condition. Trade-in credit trades some of that value for convenience and zero listing effort.
Do I need to factory reset my phone before trading it in? Yes, always, and remove Activation Lock or the equivalent account lock first. A locked device is effectively unsellable.
Does AT&T pay trade-in value as one payment? No. AT&T typically spreads it as bill credits over a 30-month term rather than paying it out at once, so factor that timeline in before comparing it to a one-time cash sale.
