Once Samsung launched the Galaxy S10, S10 Plus, and S10e, the company decreased the maximum amount you could get from a trade-in from $550 to $300. The good news is that Samsung raised the trade-in maximum to $400, though there are some caveats.

First, the boosted trade-in value is only available if you buy an unlocked Galaxy S10, S10 Plus, or S10e. Don’t fret if you’re a Verizon, AT&T, T-Mobile, or Sprint customer — you can still get up to $300 off carrier versions when you trade in an eligible device.

Also, only the following smartphones net you the full $400 credit:

• Samsung Galaxy Note 9
• Samsung Galaxy Note 8
• Samsung Galaxy S9/S9 Plus
• Apple iPhone XS/XS Max/XR
• Apple iPhone 8/8 Plus
• Apple iPhone X
• Google Pixel 3/3 XL
• LG V40 ThinQ

Finally, the new trade-in deal is available for a limited time in the U.S. Samsung didn’t say for how long the deal will last for, so you might want to buy the Galaxy S10 sooner than later if you want a higher trade-in offer.
