Realme Secret Codes & USSD Dial Codes (2026)
Realme UI codes & fixes
Realme secret codes are short USSD and MMI sequences typed directly into the phone dialer that open diagnostic screens, service menus and network information panels normally hidden from the standard settings app. They let you inspect the hardware and firmware of your Realme device without installing anything.
Typical uses include checking the exact firmware build, reading battery voltage and health data, running display and touch tests, viewing the serving cell and signal strength, and displaying the IMEI. Each entry in the table below is documented publicly and labelled with a risk level so you know what will happen before you dial.
Codes execute immediately on most Android builds, with no confirmation dialog, so read the risk column carefully. Anything marked destructive erases user data the moment it is accepted by the dialer, and there is no way to cancel or undo it afterwards.

How to use Realme codes
- Open the Realme dialer and go to the keypad, exactly as if you were dialling a number.
- Type the code precisely as shown, including the leading
*and the trailing#. Autocorrect and paste can drop characters, so type it out. - Most sequences fire the moment the final character is entered — you usually do not press call.
- If the screen does not change, press the call button once; a few USSD strings need it.
- Back up photos, messages and app data before running anything marked destructive, then confirm you are on the right device.
- Nothing at all happening usually means the code is disabled on your firmware or blocked by your carrier — it is not a fault with your handset.
Realme secret codes — FAQ
¿Todos los teléfonos Realme admiten los mismos códigos secretos?
No. La compatibilidad con los códigos depende del modelo, de la versión del firmware y, en muchos casos, del operador que suministró el teléfono. Los modelos Realme más antiguos suelen ofrecer más menús de servicio que los más recientes, porque los fabricantes restringen gradualmente el acceso a las herramientas de ingeniería mediante aplicaciones de diagnóstico firmadas. Si un código no hace nada, casi con total seguridad se ha eliminado o desactivado en tu versión, en lugar de haberse escrito incorrectamente.
¿Es seguro marcar los códigos secretos de Realme?
Los códigos que marcamos como "seguros" solo muestran información o abren un menú de pruebas de solo lectura, por lo que no pueden dañar tu teléfono. Los códigos marcados como "precaución" cambian un ajuste o inician una rutina de hardware que deberías comprender primero, y los códigos marcados como "destructivos" borran los datos del usuario al instante sin un diálogo de confirmación. Haz siempre una copia de seguridad antes de ejecutar cualquier código de la categoría destructiva.
¿Por qué no ocurre nada cuando introduzco un código?
Hay tres motivos habituales: el código no es compatible con tu firmware, tu operador de red ha bloqueado la cadena USSD o el marcador requiere que pulses el botón de llamada para esa secuencia concreta. Prueba el código con otra SIM o en modo avión y comprueba cada carácter, incluidos el asterisco inicial y la almohadilla final.
¿Usar estos códigos anulará la garantía de mi Realme?
La simple lectura de información de diagnóstico no anula la garantía. Sin embargo, cambiar los ajustes de bandas de radio, ejecutar operaciones de escritura en un menú de ingeniería o realizar un formateo de fábrica puede dejar el dispositivo en un estado que un servicio técnico podría considerar causado por el usuario. Limítate a los códigos de solo lectura, salvo que sigas instrucciones oficiales de reparación.
¿Pueden estos códigos liberar un teléfono Realme con bloqueo de red?
No. La liberación de red requiere un código de desbloqueo proporcionado por el operador o una solicitud oficial de liberación a través de tu operador. Cualquier sitio que prometa un código de marcación universal y gratuito para desbloquearlo te está engañando. Los códigos que se enumeran aquí solo dan acceso a diagnósticos, estado de la red, información del firmware y rutinas de restablecimiento de fábrica.
¿Cómo encuentro mi IMEI en un dispositivo Realme?
Marca *#06# en cualquier teléfono GSM o LTE, incluidos todos los modelos Realme, y el IMEI aparecerá inmediatamente. También puedes validar el número con nuestro comprobador de IMEI, que calcula la suma de verificación de Luhn utilizada por la GSMA para detectar números IMEI mal escritos o inventados.
