If you have more than 2 people in your organization, then this will save you so much time. Delegation is the key to starting a business. Even when you're a 1 person show, being able to present to your user base the differentiation of options for client communications is critical. As a founder, feeling compelled to be always on is something I strive not to be. OpenPhone gives you that flexibility. I have found it to be less appropriate in complex HIPPA compliant areas, but that is it. OpenPhone really does seem to suit an open array of use cases.

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.

  • 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
OpenPhone
  • Call quality can be spotty on wifi if the connection is poor, but nothing they personally can do about that. 4G LTE is usually stronger and more stable.
  • N/A honestly excellent product for the price.

  • 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.

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.

OpenPhone has an easier user interface than Grasshopper. Years ago when I was using Grasshopper, I recall that their user interface looked antiquated and full of complications. They would also update the interface just as everyone was getting used to using it. OpenPhone has many more functions. Grasshopper's app did not offer basic functions such as in-app texting between team members, and its call transfer function was incredibly complicated to use. In my opinion, Grasshopper was an inferior service/product in almost every way.

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.

  • 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.
