How to fix Viber not working
Viber is up on our end, so if it won't work for you, the problem is most likely on your side. Work through these in order:
Your browser tries to reach viber.com over your own connection, right now. Nothing is sent to us or stored.
Switch networks and reconnect
Open a chat and send a message. A clock icon next to it means the app cannot reach the servers. Toggle airplane mode on for a few seconds and off again, or move from Wi-Fi to mobile data; if every other app loads and Viber still will not connect, the app is the problem.
Force close and reopen the app
Swipe the app away from the recent apps list and launch it again. A stuck background process can leave calls ringing with no audio, or messages sitting unsent while the phone has a solid connection. Give it a few seconds before you test a call.
Clear the app cache on Android
Go to Settings > Apps > Viber > Storage and tap Clear cache. That clears temporary files and leaves your chats alone. Do not tap Clear data, which wipes the local copy of your message history. On iPhone there is no cache button, so delete the app, install it again from the App Store, and sign in with your phone number.
Check microphone and notification permissions
Calls that connect with silence usually mean the microphone permission is off. On Android check Settings > Apps > Viber > Permissions, and on iPhone check Settings > Viber and turn on Microphone. Missing notifications work the same way: check the toggle inside the app under Settings > Notifications and the one in system settings. If none of this helps, the help centre at https://help.viber.com/ covers account and login problems.
While Viber is down: what to use instead
- Regular call or SMS A normal phone call or text runs over your mobile carrier instead of the internet, so it still reaches people when your chats won't send or calls won't connect.
- WhatsApp Plenty of your contacts likely have it already, and it signs you in with your phone number.
- Telegram It suits group chats because you can post one invite link and move the whole group over in a minute or two.
- Signal Use it for private one-to-one calls and messages, since it encrypts them end to end by default.
Fix Viber on Windows, Mac, Android and iPhone
Viber on Windows

Viber on iPhone and iPad
- Fix
- Force close and restart Viber, check the Apple App Store for any pending updates, or restart your iOS device.
- Check
- If Viber on your iPhone or iPad fails to deliver push notifications or is stuck on the 'Connecting' screen, the servers may be experiencing an outage.
What happens when Viber goes down
Viber is a messaging and calling app for phones and desktops, used by families and people calling abroad, so an outage cuts off chats, group calls, photo and file sharing and desktop login all at once. The figure above counts user problem reports in 15-minute windows over the last 24 hours; it does not ping or probe the service.
Messages often hang on sending before calls fail, and a chat can show as delivered on your phone while the desktop app stays stuck on the QR login screen. Group chats slow to a crawl, photos stall, voice notes stall, and outbound calls drop at the ringing stage or never connect. The trouble is often partial: one country, one carrier, the mobile app or the desktop client goes bad while the rest of the service keeps working. If the app opens but nothing sends, check the help centre before you reinstall.

How we track Viber
The status on this page comes from user-submitted problem reports for Viber, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for Viber, so a few complaints on a quiet day don't trigger anything, but a sudden jump well above normal does.
When reports climb well above normal, the status here changes to partial outage or major outage and the chart moves with it. Viber doesn't publish a public status page that we know of, so user reports are often the quickest sign that something is wrong on their side.
