As mentioned previously, it is easy to use and access since the you can chat, send voice memos or stickers in a conversation. So in overall it's very entertaining. But throughout that, the audio quality can seem to be a bit off. (Could be personal headset issue) Overall that is the only issue that is present or consistent.

Signal is great for high-security applications where privacy is a concern, perhaps because of the sensitive nature of the materials being communicated. For instance, if you are sending sensitive information about a film that hasn't been released yet, and you want to make sure that paparazzi and fans don't get access to spoiler information, Signal is a great way to communicate.

Pros
Rakuten Group
  • Viber is a cross platform product. It does not matter if someone uses Android or iOS device, it will work exactly the same.
  • Also the desktop version is very good. You can switch between the desktop and mobile versions within a conversation and see updates right away.
  • It's a very international product. It has been available for very long time, which makes it very wide spread - it has a good user base.
  • You can see the status of your messages.

Cons
Rakuten Group
  • When someone sends a file in Viber, the program automatically saves it in your phone memory. This means that you must delete them manually and it really annoys me, as it takes a lot of time to do that.
  • It contains enormous amounts of adds.
  • There is file sharing limit.

  • Update Hassle - While this is also a positive in added security, every time they release an update to the app, you have to update. Since I only use the app occasionally, I have to update probably 1-in-4 times I open the app. It feels laborious as I will sometimes want to send a friend or colleague a message, who only uses Signal, and I open the app to message them and suddenly have to wait 2-4 minutes to update and install the new version.
  • Not Getting Messages - You also no longer send and receive messages until you update. So if you have an outdated version of the app, nobody can get ahold of you and they might not know why you aren't responding.
  • Re-Sync Via QR Code After Update - Every time I update, I have to re-sync my mobile app to the desktop. So it adds another added step. The forced updates and forced resync steps are quite laborious.

I have not frequently used the support for Viber as I have not had many problems with it on my phone. I did use support one time for problems with the computer application and used the forums to solve my problems. They were fairly easy to follow and I appreciated the online help in that format.

You don't really need support as the app just works. In the two plus years I've been using Signal, I've never needed to even look at support documentation to learn how to do something or have the app work. It just does. The best support is not needing to use it, and Signal meets that standard.

End-to-end encryption scrambles my messages and delivers them as a scrambled code to my friend's device, whether mobile or desktop, so that only their device can decode them into plain text. If my friend's phone is turned off or they don't have access to the internet, my message will be stored on Viber's servers (for a limited time) until their device is ready to receive it.

Because Viber can't access or read my private conversations in the first place, Viber can't sell them.

The closest competitor we've found for Signal is Telegram. We do use Telegram with some clients and individuals who prefer it. Unfortunately, in this climate where there is no clear winner and a lot of diversity in applications, if you work with a lot of clients you're going to have to install a whole suite of instant messaging apps. Still, given the choice, we prefer Signal over its competitors, specifically for applications where high security is a concern.

Return on Investment

  • Viber saves me financially since I am now able to communicate with my international clients for free.
  • Viber helps keep my clients engaged by the fact that I can so easily share photos, which is important as a freelance photographer.
  • Viber allows me to make my messages to clients appealing in a visual way, which I have noticed helps drive actions of my clients, such as remembering to book their next session or pay for their photo order.
