Viber Not Receiving Incoming Calls? How to Fix It

If Viber calls are not reaching you, allow Viber notifications, turn off battery limits for the app, and check that it can run in the background.

Most common causes

• Notifications for Viber are off or silenced.
• Battery saver stops Viber running in the background.
• Do Not Disturb or Focus mode blocks calls.
• Viber is not allowed to use mobile data.
• The caller is blocked, or you are on an old Viber version.

Android fixes

1. Open Settings › Apps › Viber › Notifications and allow calls.
2. Under Battery, set Viber to Unrestricted.
3. Allow background data.
4. Check Viber has permission to show over other apps, so the call screen can appear.

iPhone fixes

1. Go to Settings › Notifications › Viber and allow notifications.
2. In Settings › Viber, allow mobile data and background refresh.
3. Check Focus modes in Control Center.
4. Turn on Viber's option to show calls in the iPhone call screen, if available.

Inside Viber

Network

Viber calls need internet. A weak or captive Wi-Fi network, such as hotel Wi-Fi needing a login page, can stop calls arriving. Switch to mobile data to test.

Viber on several devices

If Viber is on a computer as well, calls may ring there first. Make sure the desktop app is closed or set to let calls ring on your phone.

Still missing calls

• Update Viber from the app store.
• Restart the phone.
• Reinstall Viber after backing up chats.

Messages not arriving either? See Viber blocked messages.

Calls ring but cannot be answered

If the call rings but drops when you answer, Viber may lack microphone permission or the network may block call traffic. Allow the microphone in app permissions and test on mobile data.

Viber Out is different

Viber Out is the paid feature for calling regular phone numbers from Viber. It is for outgoing calls only. People calling your normal number reach you through your phone app, not Viber.
