The Samsung Galaxy S23 launched in 2023 as the compact flagship in Samsung's S23 line, aimed at buyers who wanted Ultra-level performance in a one-hand-friendly body. In the US it ships as SM-S911U, running the same Snapdragon 8 Gen 2 for Galaxy chip across AT&T, T-Mobile, Verizon and unlocked units. Its metal-and-glass build, 120Hz AMOLED screen, and a camera bump-free design gave it staying power, and demand for a clean 128GB, 256GB or 512GB unit has stayed steady since. Pick your carrier, storage, and condition above for a live cash offer. If you want the mechanics first, see how the process works, or head straight to sell your smartphone once you know what you're holding.

Confirm you have the Galaxy S23

Open Settings → About phone → Model number. That string tells you the exact SKU and, on some carrier builds, whether it's still network-locked. If the screen won't turn on, the model number is also printed on the SIM tray or in the original box.

SM-S911

  • General international reference for the Galaxy S23
  • Used loosely across regions but not the exact US retail string

SM-S911U

  • The model number for all US units: AT&T, T-Mobile, Verizon, and unlocked
  • Same Snapdragon 8 Gen 2 hardware regardless of carrier
  • Carrier lock status is separate from the model number and matters for resale

Prefer a visual check? The S23's three rear cameras sit as individual lenses rising straight off the frame, with no raised camera plate behind them. If your phone has a metal bump housing all three lenses together, it's an S22, not an S23. The S23 also measures about 6.1 inches corner to corner; if it feels noticeably larger in hand, you likely have the S23+.

Launched on One UI 5.1 over Android 13. Samsung committed to multiple years of OS upgrades and security patches for this generation, so a used unit can still be running current software.

Frequently asked questions

01 How do I find the model number or exact configuration?
Go to Settings → About phone → Model number to see the exact string, which for US units reads SM-S911U regardless of carrier. To check storage, go to Settings → Battery and device care → Storage, where the total capacity is listed at the top. Carrier lock status can be checked under Settings → Connections → Mobile networks, or by inserting a SIM from a different carrier and watching whether it connects. If you no longer have the box or original receipt, the model number on-screen is the most reliable source.
02 How do I tell it apart from the Galaxy S22?
Look at the back camera housing. The S22 base model has a metal plate behind all three lenses, while the S23 drops that plate entirely, with each lens rising straight from the frame, matching the design Samsung used on the S22 Ultra. Screen size is nearly identical between the two at 6.1 inches, so the camera housing is the fastest tell. If you're still unsure after that, the model number under Settings → About phone will start with SM-S901 for the S22 and SM-S911 for the S23.
03 Can I sell it with damage, a weak battery, or if it won't turn on?
Yes, damaged and non-functional units are accepted, and the condition picker above accounts for cracked screens, battery wear, and dead units. Before shipping, you must remove your Google account and disable Factory Reset Protection under Settings → Accounts, and sign out of your Samsung account. A phone still locked to either account cannot be resold and will affect the offer. If the device won't power on, you can still send it, but be aware any account locks in place at time of shipping can't be worked around after the fact.
04 What raises the trade-in value the most?
Condition and completeness move the offer more than anything else. A screen free of cracks, a battery that still holds a reasonable charge, and a body without bends or corrosion all help. Higher storage tiers, meaning 256GB or 512GB over 128GB, tend to hold value better since they're less common used. An unlocked unit, or one clearly paid off and unlocked by its carrier, is worth more than one still tied to a balance. Including the original box or cable can help slightly but matters far less than the phone's own condition.
05 How do I erase it and remove my accounts, and how do I get paid?
Start by backing up anything you want to keep, then go to Settings → Accounts and remove your Samsung account and Google account one at a time. Next, go to Settings → General management → Reset → Factory data reset and confirm. This clears Factory Reset Protection along with your data, so the next owner can activate the phone without your credentials. Once you've submitted your order on this page, shipping is free and insured, and payment goes out after inspection by PayPal, Venmo, Zelle, CashApp, or check.
