Phonecheck Verified Used iPhones

Every used iPhone at Coolmix goes through a detailed device testing process powered by Phonecheck. We use Phonecheck’s professional mobile device diagnostic platform to test and verify key functions before the devices are made available for wholesale.

Professionally Tested Before Sale

Our used iPhones are tested for essential hardware and software functions, helping us identify potential issues before devices reach our customers. From device functionality and battery information to connectivity, sensors, display and other critical components, each phone goes through a systematic diagnostic process.

Tested, Graded & Ready for Wholesale

After testing, devices are assessed and categorized according to their condition and grade. This allows buyers to source used iPhones with clearer information about device quality and condition, making bulk purchasing easier and more transparent.
