Frequently Asked Questions
Everything you need to know about USSD codes, device support, and diagnostics safety.
Secret codes (also known as USSD, MMI, or service codes) are sequences of numbers, asterisks (*), and hashes (#) that interact directly with your device firmware or carrier network to open hidden engineering menus, diagnostic screens, and system data.
Yes, the overwhelming majority of codes in Mobile Secret Codes are read-only diagnostic and informational codes (such as checking your IMEI with *#06#, viewing battery health, or testing your screen). Any advanced configuration or reset codes are clearly marked with warning indicators so you remain in complete control.
