When a message is sent to you via WhatsApp, but you do not have the app open to receive it, your iPhone will automatically display a push notification to alert you of the message. iOS apps can provide three types of notifications:

• Sounds: An audible alert plays.
• Alerts/Banners: An alert or banner appears on the screen.
• Badges: An image or number appears on the application icon.

WhatsApp Calling Notifications

There are two ways to answer a WhatsApp call based on your notification settings:

• Alerts: To answer a call from an alert, tap on Accept. To decline a call, tap on Close.
• Banners: To answer a call from a banner, tap on the banner on the top of the screen. To decline a call, simply ignore the banner.

Note: With iOS 10 and call integration, the ringtone used for WhatsApp calls is the ringtone set in the Contact's information within iPhone Settings.

Setting up notifications

Please verify that your notification settings are turned on in both your WhatsApp and iPhone settings:

• Go to WhatsApp > Settings > Notifications and check that Show Notifications are enabled for Messages and Groups.
• You can turn off the vibration or sounds you experience in the app, for example the sounds you hear when you send or receive messages. Go to WhatsApp > Settings > Notifications > In-App Notifications.

• Go to iPhone Settings > Notifications > WhatsApp. Set your preferences for Alert style (Banners, Pop-up alert, or None), Badges, and Sounds. If you want notifications to appear when your phone's display is off, enable Show on Lock Screen.

The alert sound volume is controlled by your iPhone's ringer volume, which can be set in iPhone Settings > Sounds. Here, you can also set your Vibrate preferences.

Troubleshooting notification problems

If you have verified that your notification settings are correct in both iPhone settings and WhatsApp settings and you do not receive notifications, this is more than likely an issue with your connection, iOS or Apple's Push Notification Service.

Please note that delivery of notifications is controlled entirely by Apple's Push Notification Service (APNS), and WhatsApp has no way to resolve issues with this service. If someone sends you a message while you are offline, that message will be sent to APNS to be delivered to your phone. WhatsApp has no control or visibility over the delivery of these notifications. The issue may be presenting itself in WhatsApp, but the issue derives from APNS or the iOS.

Typically, the only way to resolve this issue is to restore the phone to factory settings and set the phone up as new. If you restore a backup, you will likely restore the issue as well.

Also note that push notifications require a valid SIM card and an active Wi-Fi or cellular connection.
