The Samsung Galaxy S24 Unlocked launched in 2024 as the compact option in Samsung's flagship line, built for people who want top-tier performance without the size of the Plus or Ultra models. It ships carrier-free, model SM-S921 (also seen as SM-S921U1 or SM-S921ULBEXAA depending on where it was bought), and works across AT&T, T-Mobile, Verizon, or any GSM network without an unlock request. It holds value well because Samsung backs it with a long software support window and because the unlocked variant is the most flexible resale configuration on the used market. Pick your storage tier and condition above for a live cash offer, or read how the process works before you commit. When you are ready, you can also start from the general sell your smartphone page.

Confirm you have the Galaxy S24 Unlocked

Open Settings → About phone → Model number to see the exact SM-S921 variant. The same screen shows the IMEI, which you can cross-check by dialing *#06#. Carrier-branded units usually show a different suffix, so if your model number ends differently, use the carrier options on this page instead of the unlocked one.

Frequently asked questions

01 How do I find the model number and exact configuration?
Go to Settings → About phone → Model number to see whether you have SM-S921U1 or SM-S921ULBEXAA. The same menu shows the Android version and build number. Storage is listed under Settings → About phone → Storage, and you can also check total memory used versus available there. If you bought the phone new and kept the box, the sticker on the box repeats the full model number and storage tier, which is the fastest cross-check if the phone will not power on.
02 How do I tell it apart from the Galaxy S24+?
Size is the fastest tell. The S24 has a 6.2-inch display and feels notably smaller and lighter in hand than the 6.7-inch S24+. Both share the same design language and camera layout, so if you are unsure, check Settings → About phone → Model number: the S24 shows SM-S921, while the S24+ shows SM-S926. Battery capacity also differs, with the Plus rated higher, though that is not something you can check without opening battery health tools.
03 Can I sell it with damage, a weak battery, or a locked account?
Yes, most damage conditions are accepted and reflected in the condition grade you select above, including a cracked screen, a battery that no longer holds a full charge, or a phone that won't power on. What is not negotiable is the account lock: Samsung account and Google account must both be removed before the phone ships, and Find My Mobile needs to show the device as removed. A phone still tied to an account or showing activation lock cannot be resold and will typically be rejected or returned.
04 What raises the trade-in value the most?
Condition and completeness move the offer more than any other factor on this model. A screen free of cracks, a battery that still holds a reasonable charge, and a body without bends or corrosion all push the quote higher. Beyond condition, the 256GB storage tier and an unlocked carrier status both sit at the top of the resale range, since they suit the widest pool of buyers. Including the original box or cable helps a little but matters far less than the physical state of the phone itself.
05 How do I erase it, remove my accounts, and get paid?
Start at Settings → General → Reset → Erase all data (factory reset), then confirm. Before that, sign out of your Samsung account under Settings → Accounts and backup, and remove your Google account under Settings → Accounts. Check Settings → Security and privacy → Find My Mobile and disable it, since a phone still linked here can't be resold. Once the device is wiped and unlinked, ship it in using the free, insured label from your quote. Payment goes out after inspection, by PayPal, Venmo, Zelle, CashApp, or check. Full steps, including what to do if you forgot your password, are on the data erasure protocols page.
