The Real Trade-In Math
When it's time to upgrade or sell your old phone, you've got options: carrier trade-in, retail trade-in (Best Buy, Apple Store), or selling to a local cash buyer like CashForPhonesAZ. The difference in what you actually pocket can be hundreds of dollars.
iPhone 15 Pro Example
| Option | Offer | Form | Notes |
|---|---|---|---|
| AT&T Trade-In | Up to $350 | Bill credits | Locked into new contract; credits over 36 months |
| Best Buy Trade-In | Up to $280 | Gift card | Best Buy store credit only |
| ecoATM Kiosk | $120–180 | Cash | Variable, often low, kiosk only |
| CashForPhonesAZ | Up to $400 | Cash/Zelle | Same day, no contract, real money |
The Hidden Catch with Carrier Trade-Ins
Carrier trade-in offers look great on paper — "Get up to $800 for your old phone!" But that value comes as bill credits spread over 24–36 months. You only capture the full value if you stay with that carrier and that plan for the entire period. Switch carriers or cancel? You lose the remaining credits.
Cash is different. Cash is real. You can use it however you want — apply it to any phone, any carrier, any purchase. No strings attached.
When Trade-In Makes Sense
Carrier trade-ins make sense if you're already upgrading with that carrier and the credits apply immediately to your new phone purchase. In that narrow scenario, they can match or beat cash. But if you want flexibility — or if you're not upgrading right now — cash wins.
