In older versions of iOS, you can change your
toques para whatsapp by going into Settings and selecting "Sounds and Haptics." Tap on Ringtone under that menu, then tap the ringtone you want to use as an alert sound.
You can also set your ringtone for various notifications in Apple's built-in apps. You can select a different sound for incoming calls, text messages, new voicemail, sent mail, reminders and calendar alerts.
