IMEI, carrier history, and blacklist checks
IMEI history, carrier-lock status, and blacklist checks confirm each device is carrier-cleared and blacklist-clean before it moves downstream, the carrier background check buyback and ITAD operators depend on.

Common questions.
Which watches and AirPods does Phonecheck support?
Apple Watch Series 4 and newer on watchOS 10 or later, through the Pairing method; Galaxy Watch4 and newer; and every generation of genuine AirPods, including AirPods Max.
How many can one station process at once?
Up to 15 Galaxy Watches at the same time, Phonecheck's recommended maximum per station. Apple Watches run one after another through one prepared iPhone, and several sets of AirPods can be processed at the same time.
How are watches and AirPods cleared?
Each watch is erased, and an erase certificate is generated. Phonecheck detects and erases the eSIM on cellular Apple Watches. AirPods get a guided factory reset, recorded with the set's results.
Does Phonecheck detect locked watches?
Yes. Phonecheck detects Activation Lock on Apple Watch and account locks on Galaxy Watch. Checking accounts at intake keeps locked units out of your stock.
Do wearables get a Device History Report?
Galaxy Watches, Apple Watches tested on the HUB method and AirPods each get a Device History Report, the same record buyers see for your phones.
What does a wearables station need?
For watches, a Mac or Windows PC running Phonecheck 3, plus an Android phone on Android 7.0 or later for Galaxy Watch, or an iPhone on iOS 17 or later for Apple Watch on the Pairing method. AirPods need a Mac on macOS Sonoma or later.
Are AirPods still signed in to iCloud flagged?
Yes. A set still signed in to iCloud is recorded as a defect, on by default, and the defect shows on the label, the cloud record and the Device History Report.
