WhatsApp vs Viber – Which One Offers Voice Calls, But One Of Them Is Better

0

Messaging applications are becoming more popular by the day, and it seems that they’re becoming a replacement for the traditional method of placing a telephone call. Cell phone providers are offering cheaper mobile plans with more megabytes, so that their clients can surf the internet without worrying that they’ll exceed their monthly data usage plan. There are many applications offering voice calls, but in fact, they eat data and within a few hours, the users remain without their available megabytes. This article is a comparison between two very popular applications, WhatsApp and Viber, and we’ll take a look at their features and call quality.

Compatibility

WhatsApp can be installed only on smartphones running on iOS, Android, Windows Phone, BlackBerry 10, Series 40 and Symbian, and there is a web version that allows the users to log into their accounts from a computer, but for now, iOS isn’t supported due to “platform limitations”. Viber is more generous when it comes to supported platforms, having versions even for Mac OS, Bada and Linux, but before being installed on a computer, first, the users must use their smartphones and to enter their phone numbers for verification.

Ease of use

WhatsApp will charge its users after one year and the annual subscription is 0.99 dollars, a very small amount of money which can be paid by any pocket. When the user installs WhatsApp, the application scans his/her phone books for numbers registered that are associated with WhatsApp and automatically adds them to the contact list. Then, the user can start personalizing his/her account, by adding a profile image and updating the status. However, WhatsApp can be used only on one smartphone. Viber has a friendly interface and it also syncs to the phone’s contacts.

Voice Calls

Viber offers VoIP calls, meaning that, besides calling other Viber friends, the users can make a call to mobile or landline numbers at very low rates. There is a service called Viber Out which requires credit and the users must pay using their credit cards or paypal accounts. The calls have HD quality and they consume around 250KB per minute or 14MB per hour.

WhatsApp introduced the voice calling feature back in February and at first, it had some problems – echoes, interruptions or lags, but the developers improved it and currently, the only problem is the high data usage: 1 minute eating 330KB. But WhatsApp still doesn’t offer HD quality calls.
