Viber — is not just a chat; it is, first and foremost about calls. Unlike Telegram or WhatsApp, Viber's architecture is very sensitive to network quality. If VoIP protocols are blocked in your country or office, the communication quality drops to zero, or the app fails to connect entirely.
Many try to enable a VPN, but this "kills" the battery and slows down the entire phone. Viber offers an elegant solution — a built-in proxy client.
This guide will show you how to configure a proxy inside the app so that calls are clear and messages arrive instantly, even if the messenger is blocked.
📌 Part 1. What kind of proxy is needed for Viber?
Before moving to the settings, you need to understand the technical side. Viber transmits data in two streams:
TCP (Text and images): Reliable message delivery.
UDP (Calls and video): High-speed data stream for voice.
The main mistake of beginners: Buying an HTTP proxy. Viber does not support HTTP proxies. It requires protocols capable of working with binary traffic.
The best choice for Viber:
SOCKS5 (Recommended): A universal standard. Fast, supports UDP. Ideal if Viber is simply "glitchy" or partially restricted.
ShadowSocks: A special obfuscation protocol. Choose this if you are in countries with total internet censorship (China, Iran, Turkmenistan), where regular SOCKS5 is detected and blocked.
🧩 Part 2. Which proxy type to choose for Viber?
Understanding the protocol (SOCKS5) is only the foundation. The walls and roof are the IP address type. The IP you choose determines whether calls will "stutter" and whether your number will be blocked for suspicious activity.
Here is a breakdown of the three main proxy types as they apply to Viber.
A. Residential Proxies
These are IP addresses of real home providers (like your home Wi-Fi). To Viber, they look completely natural.
Important choice: Static vs. Rotating
For messengers, this is a critical point.
Static (ISP Static): The IP address is assigned to you exclusively and does not change.
Verdict for Viber: IDEAL. You mimic a regular person sitting at home. A stable IP ensures continuous connection during a call.
Use case: Personal accounts, long conversations, business correspondence.
Rotating: The IP changes automatically.
Verdict for Viber: DANGEROUS. Changing the IP during a call will lead to a connection break ("Reconnecting...").
Use case: Only for mass mailing (spam) or registering thousands of accounts (farming). Not suitable for regular communication.
B. Mobile Proxies (Mobile 4G/5G)
The elite of the proxy world. These are IP addresses of cellular operators. Viber's security systems are most loyal to them, as thousands of real people can hide behind a single mobile IP (CGNAT technology).
Protocol | Task in Viber | Why it's cool |
SOCKS5 + Mobile | Bypassing hard bans and registering new numbers | If your number has already been "shadow banned" or you are in a region with strict censorship, a mobile proxy is the only chance to be "one of their own." Highest trust level. |
C. Datacenter Proxies
The most common and cheapest option. These are IP addresses from data centers (Amazon, Hetzner, etc.).
Access Type: Dedicated vs. Shared
The rule here is: "You get what you pay for."
Dedicated (Private / Individual): You are the sole owner of the IP.
Pros: Speed. Server channels are very fast, resulting in low ping (latency) in voice. Sound will be cleaner than on mobile proxies.
Use case: Bypassing Viber blocks at work or in a country if your account is "clean" and old.
Shared: One IP is used by 10-50 people.
Risks: If your IP "neighbor" starts spamming on Viber, the entire IP gets blacklisted, and your number will be blocked too.
Verdict: Not recommended for personal Viber. Saving $1 is not worth losing 5 years of chat history.
🏆 Final Summary: What to buy?
For ideal call quality: Choose Dedicated Server (Private IPv4) or Static Residential (ISP). The main requirement is low ping and stability.
For the highest trust: Choose Mobile proxies.
Protocol: Always strictly SOCKS5.
👉 Important: When purchasing, look for the "UDP Support" label. Without it, Viber will turn into a pager (text only).
🔧 Part 3. Step-by-Step Setup (Android/iOS)
The setting is hidden deep in the menu, but thanks to the screenshots, we will complete this process in a minute.
Step 1. Entering the hidden menu
Open Viber and tap on the "More" button (three dots or lines at the bottom).
Go to the "Settings" section (gear icon).
Select "General".

Fig. 2. Selecting "General" in the settings list.
Step 2. Activating the Proxy
In the "General" menu, scroll down. Find the "Use proxy server" item.
By default, it says "None".
Tap on this item to enter the configuration menu.

Step 3. Entering Data (The most crucial stage)
In the window that opens, perform the following actions:
Turn on the switch in the upper right corner (the checkmark will become active).
Select the protocol type (Type): Tap on the Type field. In the drop-down list, select SOCKS5. (Note: If your provider gave you ShadowSocks, select that, but most paid proxies require SOCKS5).
Fill in the server data: Enter the server IP address (e.g., 51.77.190.xxx) and Port (e.g., 9595).
Authentication: Enter the Username (Login) and Password for the proxy from your CyberYozh App dashboard.

⚠️ Step 4. The checkbox that decides everything (Call issues)
At the bottom of the screen, there is an inconspicuous setting "Use udp".
Be sure to check this box!
If the box is checked: Voice call traffic will go through the proxy. You will be able to make calls bypassing blocks.
If the box is not checked: Only text messages will go through the proxy.
Step 5. Verification and Saving
After entering the data, tap the checkmark in the upper right corner to save. Viber will automatically check the connection. If everything is correct:
The status in the menu will change from "None" to the proxy's IP address.
The chat background may refresh for a second (reconnection).

If the status changes to "Disconnected" or "Error" — double-check the login/password and ensure that your proxy supports SOCKS5.
💡 Part 4. FAQ and Troubleshooting
1. Calls go through, but there is a delay (lag). Most likely, the proxy server is located too far from you. Solution: Use a proxy with a geo-location close to you. If you are in the RF and the proxy is in the USA, the ping will be high. Choose Europe (Finland, Germany, Netherlands).
2. Viber says "No network" after enabling the proxy. You made a mistake in the port or password, or the proxy has "died." Solution: Try disabling the proxy in the settings. If the internet returns, the problem is with the purchased proxy.
3. Fast battery drain? This is a myth. Unlike a VPN, which encrypts all phone traffic, the proxy in Viber works only for the app itself. The impact on the battery is minimal (less than 1-2%).
Conclusion
Setting up a proxy in Viber takes just two minutes and returns your freedom of communication. You no longer need to turn the VPN on and off just for one call to relatives or a business partner.
For stable voice communication, we recommend using private SOCKS5 proxies with UDP support. This will ensure HD Voice quality even in poor network conditions.
