The Samsung Galaxy S25 Ultra, released in 2025, is Samsung's flagship phone for buyers who want the largest screen, the most capable camera system, and a built-in S Pen without stepping outside the Galaxy S line. It replaced the S24 Ultra at the top of the lineup and carries model numbers SM-S938U1 and SM-S938UZKFXAA depending on how it was purchased. Because Samsung keeps the Ultra tier in production and in demand for several years after launch, and because Snapdragon-powered US units are prized on the resale market, this phone holds value well even a generation or two after release. Pick your carrier lock and storage tier in the configurator above, then choose the condition that matches your phone, and you will see a live cash offer immediately. If you want to know what happens after you accept it, see how the process works, or go straight to sell your smartphone and start the quote.

Confirm you have the Galaxy S25 Ultra

Open Settings → About phone → Model number. That string tells you the exact SKU, which matters because carrier-locked units and unlocked units are worth different amounts. You can also dial *#06# to pull the IMEI if the phone won't fully boot into settings.

SM-S938U1

  • US unlocked retail model
  • Sold factory-unlocked, works on any US carrier
  • Typically the most flexible for resale

SM-S938UZKFXAA

  • Full carrier SKU including color code (Titanium Black shown here)
  • Sold through or activated with a specific US carrier such as AT&T, T-Mobile, or Verizon
  • May carry a carrier lock even if paid off

Prefer a visual check? The S25 Ultra has a flat titanium frame with squared-off edges, a built-in S Pen silo on the bottom edge, and four rear camera lenses arranged in a straight vertical line rather than a raised camera bump housing.

Frequently asked questions

01 How do I find the model number and exact configuration?
Go to Settings → About phone → Model number, which will show either SM-S938U1 or a longer SKU like SM-S938UZKFXAA. The same screen usually shows storage under "Storage" in Settings, and carrier lock status can be checked by inserting a SIM from a different carrier and seeing whether it connects. If the phone won't power on, the IMEI printed on the original box or SIM tray will identify the exact unit for a quote request.
02 How do I tell it apart from the Galaxy S25+?
The Ultra has a flat titanium frame with squared edges and a visible S Pen silo along the bottom, while the S25+ has rounded aluminum edges and no stylus slot. The Ultra's rear camera array also carries four lenses in a straight line, compared to three on the S25+. If you have doubts, the model number in Settings → About phone will confirm it directly, since the S25+ uses a different SM-S936 prefix.
03 Can I sell it with a cracked screen, weak battery, or a locked account?
Yes, damaged and non-functional phones are accepted, and the condition picker above adjusts the offer to reflect it. A cracked screen, a battery that no longer holds a charge, or a phone that won't power on can all still be quoted. What we cannot accept is a phone still tied to a Samsung account, Google account, or carrier that reports it lost or stolen. Remove your Google account and factory reset the device before shipping, since a locked device cannot be resold and will be returned or rejected.
04 What raises the trade-in value the most?
An unlocked, carrier-free status combined with a higher storage tier raises the offer the most. A phone fully unlocked from any carrier is easier to resell than one still tied to AT&T, T-Mobile, or Verizon, and the 1TB model commands more than the 256GB base tier. Beyond that, an intact screen, a healthy battery, and all original accessories (box, S Pen, charging cable) make a measurable difference in the condition grade you select above.
05 How do I erase it, remove my accounts, and get paid?
First back up anything you want to keep, then go to Settings → General → Reset → Factory data reset and confirm. Before that, remove your Google account under Settings → Accounts, and make sure Samsung Find My Mobile is signed out so the device isn't locked to your Samsung account after reset. Once accepted, pack the phone as instructed; shipping is free and insured. After our team tests it against the condition you selected, payment goes out by PayPal, Venmo, Zelle, CashApp, or check. Full details on wiping data safely are in our data erasure protocols.
