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 $150No cracks, strong battery, clear IMEI, unlocked, and all accounts removed. Box and charger can help the offer.

$50 to $150Light scratches, weaker battery, small frame wear, or missing charger. Still paid same day after inspection.
Broken or cracked
Around $50Cracked screen, water damage, no power, camera damage, or port issues. We still quote it for parts or repair value.
Released in 2021, Galaxy S21 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 $50 depending on what works.
Released in 2021, the Galaxy S21 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.

What we check on a Galaxy S21
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 phone is unlocked and the Google account is removed.
Offer range
$50 to $150 depending on condition, locks, IMEI status, and current market demand.

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 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.

Start your trade-inGalaxy S21 trade-in FAQs
How much can I get for my Galaxy S21?
A clean, working Galaxy S21 can pay up to $150. The full range is usually $50 to $150, 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 with a cracked Dynamic AMOLED screen?
Yes. Dynamic AMOLED panels are pricey, so a cracked Galaxy S21 is worth less than a clean one — expect around $50, but it’s still real cash on the spot.
What do you check on the Galaxy S21 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. Bring the charger to bump the offer.
What lowers the Galaxy S21 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 quote online?
Yes. Use the trade-in form on the main trade-in page. Send the model, storage if you know it, carrier or unlocked status, and condition. We still confirm the final offer at the counter.
What should I bring when selling my Galaxy S21?
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?
Yes. Once the Galaxy S21 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.
Use one trade-in form for every model
