Description
Mobile Secret Codes - MMI USSD is a handy app that can come in useful in a range of everyday situations involving your phone. When you're buying a used device, checking whether its features work properly, or trying to track down a fault, you'd normally need to call a technician for the details. With this app, you get a collection of built-in codes that reveal various information about the device's internal processes. Keep in mind, though, that some codes are not meant for every model and a few may cause problems, so use them with care.
