SMS vs. Viber SMS

What's the Difference?

SMS and Viber SMS are both messaging services that allow users to send text messages to others. However, there are some key differences between the two. SMS, or Short Message Service, is a traditional messaging service that uses cellular networks to send and receive messages. It is widely available and compatible with all mobile devices. On the other hand, Viber SMS is a feature within the Viber app that allows users to send messages to contacts who do not have the Viber app installed. It uses an internet connection to send messages, making it a more cost-effective option for international messaging. Additionally, Viber SMS offers additional features like the ability to send multimedia messages and make voice and video calls, making it a more versatile messaging platform.

Further Detail


In today's digital age, communication has become more convenient and instantaneous than ever before. With the rise of smartphones and messaging apps, traditional Short Message Service (SMS) has faced competition from various messaging platforms. One such platform is Viber, which offers its own version of SMS. In this article, we will compare the attributes of SMS and Viber SMS, exploring their features, functionality, and user experience.

1. Cost and Accessibility

When it comes to cost, SMS has a significant advantage over Viber SMS. Traditional SMS is typically included in mobile phone plans, allowing users to send messages without incurring additional charges. On the other hand, Viber SMS requires an internet connection, either through Wi-Fi or mobile data. While Viber itself is free to download and use, data charges may apply if the user is not connected to Wi-Fi. This accessibility limitation can be a drawback for users in areas with limited internet connectivity.

2. Features and Functionality

While SMS is a basic text messaging service, Viber SMS offers a range of additional features and functionality. Viber SMS allows users to send not only text messages but also multimedia messages, including photos, videos, and voice recordings. It also supports group messaging, allowing users to communicate with multiple contacts simultaneously. Additionally, Viber SMS provides read receipts, indicating when a message has been seen by the recipient. These features enhance the overall messaging experience and provide more versatility compared to traditional SMS.

3. User Interface and Experience

When it comes to user interface and experience, Viber SMS offers a more visually appealing and interactive platform compared to SMS. Viber's interface is designed to be user-friendly, with intuitive navigation and a modern aesthetic. It allows users to customize their chat backgrounds, use stickers and emojis, and even play games within the app. SMS, on the other hand, has a simpler interface with limited customization options. While some users may prefer the simplicity of SMS, others may find Viber SMS more engaging and enjoyable to use.

4. Security and Privacy

Security and privacy are crucial considerations when it comes to messaging apps. SMS is generally considered to be more secure than internet-based messaging platforms like Viber SMS. SMS messages are transmitted through the cellular network, making them less susceptible to hacking or interception. However, SMS lacks end-to-end encryption, which means that the content of the messages can potentially be accessed by service providers or government agencies. Viber SMS, on the other hand, offers end-to-end encryption, ensuring that only the sender and recipient can access the content of the messages. This added security feature makes Viber SMS a preferred choice for users concerned about privacy.

5. Cross-Platform Compatibility

One of the advantages of Viber SMS over traditional SMS is its cross-platform compatibility. Viber is available on various operating systems, including iOS, Android, Windows, and macOS. This allows users to send and receive messages seamlessly across different devices, including smartphones, tablets, and computers. SMS, on the other hand, is limited to mobile phones and does not offer the same level of integration across multiple platforms. The ability to access messages from different devices makes Viber SMS a more flexible and convenient option for users who frequently switch between devices.


In conclusion, while SMS and Viber SMS both serve the purpose of communication, they differ in several attributes. SMS offers cost-effective and accessible messaging, but lacks the advanced features and functionality provided by Viber SMS. Viber SMS, on the other hand, offers a more versatile and visually appealing platform, with additional features such as multimedia messaging, group chats, and read receipts. It also provides enhanced security and privacy through end-to-end encryption. Furthermore, Viber SMS offers cross-platform compatibility, allowing users to seamlessly communicate across different devices. Ultimately, the choice between SMS and Viber SMS depends on individual preferences and priorities, whether it be simplicity, cost, functionality, or security.
