Is It Safe to Sell Your Phone Online?
By The BuyBackBear Team · Published June 1, 2026 · Updated June 1, 2026 · 5 min read
Selling a phone online is safe, if you prepare it properly and choose a buyer that takes data seriously. Here's how to protect your privacy and avoid the common mistakes.
Key takeaways
- •Before selling your phone, back up your data, sign out of all accounts, remove the SIM card, and factory reset the device.
- •Signing out of accounts removes Activation Lock on iPhone and Factory Reset Protection on Android.
- •Reputable phone buyers re-wipe devices to NIST 800-88 standards and can provide a Certificate of Data Erasure as proof.
- •Avoid buyers with patterns of high quotes followed by low payouts, unclear revision policies, or gift-card-only payment options.
- •Look for companies that provide photo evidence when downgrading offers and offer free returns.
Wipe it the right way
Choose a buyer that certifies erasure
Reputable buyers re-wipe every device to a recognized standard (NIST 800-88) and can issue a Certificate of Data Erasure. BuyBackBear does this free on every device, so you have written proof your data is gone.
Watch for red flags
Avoid buyers with patterns of 'high quote, low payout', no clear revised-offer policy, or gift-card-only payments dressed up as cash. Prefer companies that show photo evidence on downgrades and offer free returns.
