Vivo Secret Codes & USSD Dial Codes (2026)
Funtouch / OriginOS codes
Vivo secret codes work across both Funtouch OS and OriginOS and lead to a factory test menu covering the display, multi-touch tracking, speakers, receiver, microphones, cameras, vibration motor, proximity and light sensors, gyroscope and fingerprint reader. Each test reports a clear pass or fail, which makes the menu genuinely useful when you are buying a used handset.
A quick pre-purchase routine on any Vivo device is to dial the hardware test, run the display and multi-touch checks first, then the audio loop, then the sensors. Five minutes of testing catches the faults that are expensive to fix later, and the results are far more reliable than a visual inspection.
Vivo devices also respond to universal GSM interrogation strings such as IMEI display and call-forwarding status. As always, treat reset codes as live commands: on most Vivo firmware the wipe begins the instant the sequence is accepted, without a confirmation prompt, so take a backup before you go anywhere near that category.

How to use Vivo codes
- Open the Vivo 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.
Vivo secret codes — FAQ
¿Todos los teléfonos Vivo 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 Vivo 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 Vivo?
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 Vivo?
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 Vivo 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 Vivo?
Marca *#06# en cualquier teléfono GSM o LTE, incluidos todos los modelos Vivo, 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.
