SKYPE: You buy a normal phone number in the ONE country (UK in my case) you wish to call frequently for about £30 per annum.

I currently use SKYPE to call UK numbers and these are the differences:

One of my favorite thing is that it is really reliable and private app if you ask me, they have really good privacy policy, which is very important thing for most of the people because everyone loves their privacy.Has anyone used VIBER OUT (or other international calling systems) - a calling plan whereby unlimited minutes can be purchased to phone abroad? Group messaging, chatting and group video calls are very fast and responsive without any mixing voices when people talk. It is very reliable app for transferring any kind of files, documents, photos (the quality of photo always stays high), videos etc.The quality of video calls is excellent if you comparing it to other similar apps it is definitely great, probably in top 10 apps if you ask me. After that you should get SMS verification code and basically that is it you are registered and free to use the application, for your calls, messages and much more!

Free talking, chatting and video calling application! Who doesn't need one, right? It doesn't matter if you are Android, iOS, BlackBerry or Windows user only thing that you need to do is install the app and connect your phone number with Viber app. So, let's begin, the best thing about Viber is that it is absolutely free to download and use. A multi-platform application, I can use it either from my Android phone or my laptop, because it is found in many application stores such as Google Play, App Store, and Windows, and the best thing is that there is a web platform. There is no interruption during voice and video calls, unlike many other applications. This feature was the first reason for me to get to know Viber, because through this feature I am allowed to make international calls at a much cheaper rate than the carriers, in addition to that they give you a special number. 'Viber out' feature, and the ability to give the user a private number when calling. I think it is well designed and programmed because it is a light app, and it responds smoothly to the user. The application is fast and highly responsive to the user.

Easy and good-looking app interface because of the presence of some attractive colors in the application and simple animation that gives the application a relaxing view.
