1. Viber Activation Issues

Activating Viber seems like an easy thing to do. However, many users report problems with this first, initial step. To activate Viber, you need to enter your phone number, and you should get an SMS with the activation code.

But, many users fail this step and there are a couple of reasons for that. First, you should confirm that your SIM card is valid. If it's not, you won't get the activation code. Second, Viber always requires an internet connection – cellular data or Wi-Fi.

If you don’t have access to the internet, you’ll get the message saying that it’s required. When you have access to the internet and your SIM card is valid, you should be able to receive your six-digit code via SMS. You can even get it via phone call, which is a great option.

It’s an automatic callback feature that will activate Viber as soon as you answer the call. Remember this – if you’ve requested your code 3+ times, your account will be blocked. You’ll then need to reinstall Viber and make a new account.

2. Viber Won't Send or Receive Messages & Image

Viber takes advantage of your internet when sending or receiving messages. Many users have experienced that they can’t send or receive any messages or images because their internet isn’t functioning.

When you’re inside your house, you’re probably using your local Wi-Fi network. But when you go outside, it’s necessary to use your cellular data. If your internet is working flawlessly, you should be able to send messages.

Other issues include your recipient deleting the app, so you can’t contact him through Viber. Also, there’s one more solution to this problem that works mainly for iPhone users. You need to go to Settings and then tap on Privacy. Find the Collect Analytics button and click Disable. Now, you should be able to receive and send messages freely.

3. Viber Not Ringing

Viber not ringing is perhaps one of the most persistent issues on both iOS and Android platforms. This doesn’t always have to be about your phone. Sure, you might have your ringtones disabled or you’re using a do-not-disturb profile but in many cases, this isn’t the case.

Usually, Viber doesn’t ring when your phone is locked. Your display turns on to show you the notification but you don’t hear that ‘clicking sound. To solve this, go to your Wi-Fi settings, choose Advanced, and check Keep Wi-Fi on When Screen Times Out.

Your phone may not be using the internet when it's locked, meaning that you don't receive notifications unless you unlock it. Alternatively, if you use an iPhone, you can choose a notification type in your iPhone Settings app.

In this app, click on Notifications, go to Alert Style, and choose either Alerts or Banner. This will allow you to hear your Viber messages.

4. Viber Income & Outgoing Calls not Working

Issues with incoming and outgoing Viber calls are not that rare, too. To fix it, go to Settings in your Viber app. Next, tap on Calls and Messages, and tick Viber-In-Calls. This allows your phone to receive incoming calls when someone calls you.

You can also allow Video Calls by tapping on the homonymous button and choosing On. Now, you should be able to call or receive both video and audio calls. Sometimes, Viber tends to mess up the settings, which is why you must take your time to inspect them before using it.

5. Viber Not Working on Wi-Fi

There’s a strange Viber Sleep Policy that the app sets by default. This doesn’t allow the app to connect to Wi-Fi unless you wake up your phone. We mentioned a setting similar to this just a minute ago but this one applies only to Viber, making these two completely independent.

To fix this issue, open Viber on your phone, tap on three horizontal lines at the bottom right side, and you’ll see the menu. There, tap Settings, and then General. You should see the “Wi-Fi Sleep Policy” option.

Choose Always Connected, which is the first one. The second one is the device's Wi-Fi Sleep Policy, which you don't want to use. Now, your app should work properly.

6. Viber Update Problem

Updating Viber shouldn’t be a problem if you have enough memory or you’re connected to the internet in any form. However, many users experience this issue even if the aforementioned conditions are fulfilled.

The easiest way to fix this issue is to clear cache and data. Go to your phone Settings, find App Manager (or however it’s called on your phone), and find Viber. Tap on it, and choose Clear Cache. If this doesn’t help, repeat the steps but only click on Clear Data instead of Clear Cache, and see if it works.

7. Viber Desktop Not Working

For Viber Desktop to work, you need following ports for TCP and UDP:

  • • 5245
  • • 4244
  • • 5243
  • • 7985
  • • 80
  • • 443

These ports can be opened if you go to Control Panel and find Windows Firewall. There, click on Advanced Settings, and on the left, there's Inbound Rules table. Inside, click on New Rule, and the wizard will open.

In the New Inbound Rule Wizard, click Port and Next. Select TCP and enter the ports we’ve mentioned above. Click on Next, and then Allow the Connection. Proceed until the end of the New Inbound Rule Wizard and name it Viber. Click Finish and your ports will be opened The same procedure is for UDP, so you’ll only need to choose it in the NIRL (New Inbound Rule Wizard).

Conclusion

Fixing any Viber issues shouldn’t be a problem if you followed our steps. Of course, if you have any uncommon issue, you can always contact Viber’s customer support and resolve it. Now that you have your favorite messaging app functioning, it’s time to enjoy its premium features!
