How To Make Voice Calls on Viber in 2025
Trying to stay connected without burning through your mobile plan? Viber is pretty popular for making free voice calls – whether it’s your friends across the world or that cousin you barely see. The thing is, even if it sounds simple, sometimes Viber just refuses to let you call, or you’re not sure if it’s set up right. So, this how-to is for folks who wanna make sure they’re doing everything correctly. Expect a straightforward way to get those calls going without fuss, plus some tips if it just doesn’t work right off the bat.
How to Fix Viber Voice Call Issues
Getting Viber Installed and Verified – The First Step
If your calls won’t connect at all, first things first: check if Viber is installed properly. On some devices, the app might be there, but permissions or account setup are wonky. On Android, make sure you have Google Play Store open, search for “Viber”, and hit install. On iPhone, head to the App Store and do the same. Sometimes, a quick reinstall fixes weird bugs. Also, double-check if the app has all the necessary permissions (microphone, contacts, notifications) by diving into Settings > Apps > Viber > Permissions. Because of course, Viber needs microphone access to actually talk.
Why this helps
This ensures Viber can actually detect your mic and contacts, which might be the blockers if calls aren’t going through. If permissions are blocked, the app can’t do its thing, and calls either don’t connect or sound terrible. Expect to see a better chance of successful calls afterward.
Note: If your phone has weird restrictions or you’ve recently updated your OS, permissions might have reset automatically. A quick fix is to re-enable them manually.
Account Verification and Sync
Once Viber is installed, open it up and verify your phone number. Make sure you get the SMS verification code and enter it. No code? Try tapping “Resend code”. Sometimes, if SMS doesn’t come through, Viber might not work correctly to identify contacts or initiate calls. Also, go to Settings > Privacy > Contacts and make sure Viber has permission to access your contact list. Otherwise, it can’t find people to call.
Why this helps
Verifying your number confirms you’re legit, and granting contact access lets Viber find your friends. If it’s not pretty much synced, calls stay silent or fail to initiate. Expect that once permissions are squared away, calling becomes way more reliable.
Also, on some setups, relaunching the app or even rebooting the device can give things a little boost. Sometimes, Viber just needs a restart after permissions or account tweaks.
Check Your Network & Call Settings
When calls are sketchy or dropping, poke at your internet connection. Use a stable Wi-Fi if you can, or make sure your mobile data is turned on and working. Sometimes, Viber works fine on Wi-Fi but struggles on cellular data if your carrier does weird things with VoIP traffic. Also, in Settings > Voice & Video, make sure no call blocking or restrictions are active. If you’re on an enterprise or custom ROM, there might be firewall rules messing with IP traffic.
Why this helps
Viber calls rely heavily on a good network. If your Wi-Fi or data isn’t stable, audio drops, calls disconnect, or just won’t connect at all. Expect better call stability after confirming a good network.
Additional tip: try doing a quick resetting of your network settings if calls keep failing, but remember, that’ll wipe saved Wi-Fi passwords and Bluetooth pairings first.
Another thing to try: Toggle Microphone & Sound Settings
Really weird, but sometimes the problem’s on your device’s end. Head into Settings > Sound & Vibration > Microphone (or your device’s equivalent) and make sure nothing’s muted or disabled for Viber. Also, test your mic with other apps like voice recorder or WhatsApp calls to confirm it’s working. On some phones, an app can block mic access in the background, which messes with Viber’s ability to transmit your voice.
Why this helps
If your mic is dead or blocked, no voice gets through, even if the call connects. Expect that fixing the mic permissions or hardware hiccups should clear it up.
Be aware: on some old devices, hardware issues or outdated drivers could cause audio problems that are not fixable through software alone.
Reinstall or Update Viber if Nothing Works
If all these steps don’t do the trick, consider uninstalling and then reinstalling Viber. Sometimes an update is needed to fix bugs related to calling. Also, check for app updates in Google Play or the App Store. Outdated versions can have compatibility issues, especially after OS updates or new phone releases. A fresh install clears any corrupt data or lingering bugs that might be blocking calls.
Why this helps
Reinstalling or updating often fixes bugs that aren’t fixed by simple tweaks. It’s kind of weird, but on some machines, it’s the only way to get Viber calling working again reliably. Expect to see fewer glitches afterward.
Heads up: freeing up space and clearing cache from app settings can also help if the app feels sluggish or keeps crashing.
Summary
- Make sure Viber has all required permissions (microphone, contacts).
- Verify your phone number and ensure SMS code is accepted.
- Check that your internet connection is solid (prefer Wi-Fi if possible).
- Test your mic outside of Viber to confirm hardware is okay.
- Reinstall or update Viber if calls still aren’t working smoothly.
Wrap-up
Getting voice calls on Viber to work shouldn’t be a mystery, but sometimes permissions, network, or app bugs get in the way. Going back to basics—making sure everything’s up-to-date, permissions are granted, and your network is stable—usually does the trick. If it still doesn’t work after all that, it could be device-specific or related to ongoing outages. Fingers crossed, this gets things moving again.
