## Numeros de telefono brasilenhos

<Note>
  Wappfy maneja automaticamente el problema del 9no digito brasilenho. Si un mensaje falla con un error "no LID found", el sistema reintentara automaticamente con el formato alternativo (agregando o quitando el 9no digito).

  Por ejemplo, si `5511999998888` falla, se reintentara con `551199998888`, y viceversa. Esto ocurre de forma transparente -- no necesitas manejarlo tu mismo.
</Note>
