Carrier-locked is okay
AT&T, Verizon, T-Mobile, Cricket, and other carrier locks are part of the normal quote flow.
Sell locked iPhone Chicago
Locked does not mean the same thing to every buyer.
This is where sellers get stuck. A carrier-locked iPhone can still be bought and priced. An iCloud-locked or passcode-locked iPhone cannot. Windy City Electronics buys carrier-locked iPhones in Chicago and Chicagoland, and the quote calculator on the homepage already separates locked from unlocked pricing.
iCloud-locked is not
If the phone is still activation locked to an Apple ID, it is not a deal we can do.
Passcode-locked is not
If the phone cannot be accessed because the passcode is unknown, it is not buyable through this flow.
