The Samsung Galaxy S20 Ultra 5G launched in 2020 as Samsung's flagship for buyers who wanted the biggest screen, the longest zoom, and the most camera hardware Samsung had ever put in a phone. In the US it shipped as SM-G988U across AT&T, T-Mobile, Verizon, and unlocked channels. Four years on, it still holds value because the 108MP sensor, periscope zoom, and 120Hz display remain genuinely useful specs, and because Samsung's long software support window means these units keep running current One UI releases. If you have one sitting in a drawer, pick your carrier, storage tier, and condition above for a live cash offer. See how the process works before you commit, or head straight to the page to sell your smartphone once you know what you have.

Confirm you have the Galaxy S20 Ultra 5G

The fastest way to check is on the phone itself. Go to Settings → About phone → Model number. Every US carrier and unlocked variant of this phone reports as SM-G988U, so that string is what confirms the device, not the carrier name printed on the box.

SM-G988U

  • Used across AT&T, T-Mobile, Verizon, and unlocked US units
  • Also appears shortened as G988U on some carrier invoices and IMEI lookups
  • Carrier lock status is separate from the model number and does not change it

Prefer a visual check? Look for the 6.9-inch display with almost no bezel, a rear camera module with four openings dominated by a large periscope lens, and no headphone jack on the bottom edge. If your device finder still leaves you unsure which model you're holding, the model finder tool can confirm it from a few basic details.

Core hardware

Processor

  • Qualcomm Snapdragon 865 (US and Canada market chipset)
  • Paired with 5G modem support across sub-6GHz and, on some carrier variants, mmWave

Memory (RAM)

  • 12GB on the 128GB and 256GB storage tiers
  • 16GB on the 512GB storage tier
  • RAM is soldered and not upgradable after purchase

Storage

  • 128GB, 256GB, or 512GB internal storage, matching the picker above
  • microSD card slot supports expansion beyond the built-in tier
  • Higher internal storage tiers tend to move resale value the most, since expandable storage doesn't fully offset a small built-in tier for buyers

Cameras

  • 108MP wide sensor as the primary shooter
  • 48MP periscope telephoto with optical zoom and Space Zoom digital extension
  • 12MP ultra-wide lens
  • DepthVision (time-of-flight) sensor for depth data
  • 40MP front-facing camera

Display & audio

Display

6.9-inch Dynamic AMOLED 2X panel with a punch-hole front camera and a 120Hz refresh rate option, with a software update after launch enabling 120Hz at full resolution rather than only at a reduced one.

Audio

Stereo speakers tuned by AKG with Dolby Atmos support. There is no 3.5mm headphone jack, so audio out relies on USB-C or Bluetooth.

Security

Ultrasonic in-display fingerprint sensor, plus face recognition using the front camera as a faster but less secure alternative.

Ports & connectivity

Everything routes through a single USB-C port, since Samsung dropped the headphone jack on this generation.

Wired
  • USB-C (charging and data)
  • microSD card slot (shared tray with SIM on unlocked units)
Wireless
  • 5G (sub-6GHz on all variants, mmWave on select carrier models)
  • Wi-Fi 6
  • Bluetooth 5.0
  • NFC for mobile payments
  • GPS with satellite navigation support

Battery, build & more

Battery

5000mAh battery with wired fast charging and wireless charging support, plus Wireless PowerShare for charging small accessories or another phone from the back of the device.

Finishes

Cosmic Black and Cosmic Gray were the standard finishes, with Cloud White and a Cloud Pink variant sold through select carriers.

Software

Ships on Android with Samsung's One UI. Samsung's extended update commitment for this generation means many units are still receiving security patches well past launch, which supports resale demand.

Known issues

Early units shipped with a well-documented autofocus problem on the 108MP main camera, which Samsung addressed with a software update. Worth testing focus on a moving subject before you finalize a condition grade.

Frequently asked questions

01 How do I find the model number and exact configuration?
Go to Settings → About phone → Model number and confirm it reads SM-G988U. The same screen shows your storage tier if you tap "Battery and device care" or check Settings → Storage. Carrier lock status is a separate matter and shows up under Settings → Connections → Mobile networks, or you can call your carrier if you're unsure whether the phone is unlocked.
02 How do I tell it apart from the Galaxy S20+ 5G?
Check the screen size and the camera module. The S20 Ultra has a 6.9-inch display versus the S20+'s smaller 6.7-inch panel, and the Ultra's rear camera bump is noticeably larger with a periscope lens and a DepthVision sensor that the S20+ does not carry. If you still can't tell from the outside, the model number in Settings → About phone is the definitive answer: the S20+ reports as SM-G986U.
03 Can I sell it with damage, a weak battery, or a locked account?
Yes, in most cases. Cracked screens, weak batteries, and units that won't power on can still qualify for an offer, just at a condition grade that reflects the damage. The one hard requirement is your Google account and any screen lock or Samsung account link must be removed before you ship the phone, since a locked device can't be tested or resold. Select the honest condition in the picker above so the quote matches what actually arrives.
04 What raises the trade-in value the most?
Cosmetic condition and a working display are the biggest factors, since screen replacement on a Dynamic AMOLED 2X panel is expensive and heavily affects resale. A battery that still holds a normal charge, an unlocked carrier status, and having the original box or charger also help, though none of these matter if the device is still logged into your Google account. Selecting the correct storage tier and carrier in the picker above keeps the offer accurate from the start.
05 How do I erase it, remove my accounts, and get paid?
Back up anything you want to keep, then go to Settings → General management → Reset → Factory data reset and confirm. Before that step, remove your Google account under Settings → Accounts and backup, and make sure Find My Mobile is switched off under Settings → Biometrics and security so the phone isn't locked to your Samsung account after reset. Also remove the SIM and any microSD card. Once the device is wiped, package it using the prepaid label from your quote. Shipping is free and insured, and payment goes out by PayPal, Venmo, Zelle, CashApp, or check after the device passes testing. Full step-by-step guidance is on the data erasure protocols page.
