Cash trade-in - 1054 Beach 20th Street

Sell your Galaxy S21 Ultra for cash.

Start with the central Google trade-in form, then bring your Galaxy S21 Ultra to BK Wireless in Far Rockaway for the final inspection and same-day payout. Clean working units can pay up to $220; cracked or broken units can still have value.

Released in 2021, the Galaxy S21 Ultra is an older model, but one we still buy and pay fair cash for. It’s a standard bar design with a Dynamic AMOLED panel. It also has the built-in S Pen slot, which we test during inspection.

Galaxy S21 Ultra trade-in value by condition

These are estimate ranges from the site data. Your final number depends on testing, IMEI status, account locks, and current resale demand.

Clean, working

Up to $220

No cracks, strong battery, clear IMEI, unlocked, and all accounts removed. Box and charger can help the offer.

Used or worn

$80 to $220

Light scratches, weaker battery, small frame wear, or missing charger. Still paid same day after inspection.

Broken or cracked

Around $80

Cracked screen, water damage, no power, camera damage, or port issues. We still quote it for parts or repair value.

Released in 2021, Galaxy S21 Ultra is a practical value trade-in: not the highest payout, but still worth quoting before it sits in a drawer. For older devices, account-lock status and parts condition decide whether it is worth buying. Even broken, this model can still be worth around $80 depending on what works.

What we check on a Galaxy S21 Ultra

BK Wireless does not quote only from a model name. We inspect the exact phone in front of you so the offer matches the real condition.

  • We inspect the Dynamic AMOLED screen for cracks, lines, black spots, and burn-in.
  • We check the frame, cameras, ports, and back glass before quoting.
  • We confirm the S Pen slot and S Pen response during inspection.

Offer range

$80 to $220 depending on condition, locks, IMEI status, and current market demand.

Before you sell your Galaxy S21 Ultra

Doing these first helps avoid a lower offer or a delayed payout.

Bring this with you

Photo ID, the phone, charger if you have it, and box or accessories if available.

Remove account locks

Google, Samsung, carrier, or security locks must be removed before we can accept the phone.

Back up your data

Save photos, contacts, and messages before you come in. We can help reset the phone after the deal closes.

Check repair vs trade-in

If the offer feels low because of damage, compare it against the repair price before deciding.

Repair it or trade it in?

If your Galaxy S21 Ultra is damaged but you still like the phone, repair may make more sense. If you are ready to switch, trade-in is faster and keeps the old phone from sitting unused.

  • Remove the Google or Samsung account lock before you come in.
  • Bring a government-issued photo ID.
  • Charge the phone if it powers on so we can test it faster.
  • Bring the charger, box, or case if you still have them.
  • Do not factory reset until your photos and contacts are backed up.

Compare

See the repair page first if the phone only needs a screen, battery, or charging-port fix.

Use one trade-in form for every model

All Galaxy S21 Ultra quote requests go through the central BK Wireless Google trade-in form. That keeps photos, IMEI details, contact info, and condition notes in one place.

Galaxy S21 Ultra trade-in FAQs

How much can I get for my Galaxy S21 Ultra?

A clean, working Galaxy S21 Ultra can pay up to $220. The full range is usually $80 to $220, depending on cracks, battery health, IMEI status, account locks, and whether the phone powers on. The final offer is confirmed after we inspect it.

Do you buy the Galaxy S21 Ultra with a cracked Dynamic AMOLED screen?

Yes. Dynamic AMOLED panels are pricey, so a cracked Galaxy S21 Ultra is worth less than a clean one — expect around $80, but it’s still real cash on the spot.

What do you check on the Galaxy S21 Ultra before making an offer?

Screen burn-in on the Dynamic AMOLED, battery health, IMEI/blacklist status, and that it’s unlocked with Google account removed. It also has the built-in S Pen slot, which we test during inspection. Bring the charger to bump the offer.

What lowers the Galaxy S21 Ultra trade-in offer?

Cracked glass, screen lines, burn-in, weak battery, camera damage, water damage, account locks, financed or blacklisted IMEI status, and missing parts can lower the offer. We explain the number before you decide.

Can I start the Galaxy S21 Ultra quote online?

Yes. Use the Google trade-in form on the main trade-in page. Send the model, storage if you know it, carrier or unlocked status, condition, and photos. We still confirm the final offer at the counter.

What should I bring when selling my Galaxy S21 Ultra?

Bring the phone, a photo ID, and the charger or box if you still have them. If the phone turns on, remove account locks before you arrive so the payout is not delayed.

Will I get paid the same day for my Galaxy S21 Ultra?

Yes. Once the Galaxy S21 Ultra passes inspection and you accept the offer, BK Wireless pays the same visit. No shipping, no waiting for a mail-in adjustment, and no surprise inspection later.
