A reseller's playbook: what to pay, what to inspect, the scams to spot, and how to walk away from a bad deal in under 5 minutes. Pricing as of Apr 30, 2026.
If you can resell at $19 (current market), $16–$16 leaves you a meaningful spread per unit before fees.
Pay 10–15% less for carrier-locked phones. Pay 20% less for battery health below 85%. Pay nothing if the IMEI doesn't come back clean.
Dial *#06# to surface the IMEI. Run it through any free GSMA-backed blacklist tool. Walk away on red.
Catches stolen / financed / blocked phones — the #1 cause of $0 buyback returns.Go to Settings → General → Reset → Erase All Content. If it asks for the previous owner’s account, the device is account-locked and unusable.
Forgot-to-sign-out is the most common honest mistake — but the device is worthless until fixed.On iPhone: Settings → Battery → Battery Health & Charging. On Android: a third-party app or *#*#4636#*#*.
Below 80% caps your resale tier and shaves real money off the sell price.Open Camera and Photos. Pinch-to-zoom and swipe across the entire screen. Tap each corner with a fingertip.
Flickering or dead-zone touches are repair-cost-prohibitive on most generations.Take a photo with each lens (wide, ultrawide). Switch to video, do a slow pan.
Ultrawide failure is silent — the device still functions, but resale grade drops a tier.On iPhone: Settings → General → About → Carrier Lock. Should read "No SIM restrictions" if unlocked.
Locked devices resell for 10–15% less. Verify in the menu, do not trust the seller.Pull out the SIM tray. The IMEI printed there should match what *#06# displayed.
Mismatch = the device has had its logic board swapped — these are rebuilds with unpredictable warranty status.If the seller has the box, the IMEI / serial on the box should match the one on the device.
Matching paperwork raises resale grade and signals legitimate ownership.Seller demos the device, then says they’ll sign out of iCloud / Google account later. The device arrives Activation Locked.
Tell: Insist on signing out in front of you. No exceptions.The IMEI on the screen is clean — but the SIM-tray IMEI is different. The screen-displayed IMEI was changed in software.
Tell: The two IMEIs don’t match.Seller claims their device-payment-plan was paid off. It hasn’t been — the carrier blocks the IMEI 30 days after you buy it.
Tell: Ask for the carrier release email. No email, no deal.| Scenario | Action |
|---|---|
| Excellent · large storage · >90% battery · unlocked | Buy at $6, flip at $22+ |
| Good · base storage · 85–90% battery · unlocked | Buy at $16, flip at $46 |
| Carrier-locked · DPP not confirmed paid off | Discount 15% AND demand carrier release email |
| Battery below 80% · cracked screen | Buy at $6 max, plan to sell as parts |
| Account-locked · seller claims forgot password | Walk away. The previous owner has to sign out. |
| Blacklisted IMEI | Walk away. The phone has effectively zero US resale value. |
