You can send text & pics just the same as Whatsapp, with a walkie talkie fuction added.
It works pretty much instantly, i used it for an hour last night instead of calling a mate who is in LA.
I don't use Whatsapp as it's no longer a free download (admittedly it is very cheap) so use Viber. Viber also can send location details (if you wish), texts and photos all for free. And voice calls (to other Viber members) worldwide for free (uses wifi or your data plan).
Unless you want a walkie talkie for some reason I don't see any advantage of changing from Viber (or Whatsapp).
Why I use Viber instead of Skype .. with Viber it registers your phone number. So if someone I know installs Vilber I simply use the Viber app to dial their phone number. No need to register an ID, no need to tell someone what your ID is, and (the best bit) no need to tell them to run Viber. Even if you aren't running it at all, your phone will ring if someone calls you using it (Viber will then load to alow you to answer the call).
However, unlike Skype, you can't use Viber to call non-Viber people. It's purely viber-to-viber only. Same as Whatsapp I believe.
VOIP is wonderful. I've saved loads being able to call my other half wherever I am in the world to wherever he is, so long as I'm in a place with Wifi (as I have no data plan).
And as Viber (and Skype and Whatsapp) is free for voice calls, I don't see why I should save zero and instead have to downgrade to "Hello, over!".

i use skype, voip and email with parents (which was a big surprise)
google hangouts to VC with a few friends
FB chat and WA to chat to friends
i think the more i use asynch comm tools, the less i use calls (already very little) as it seems so much more intrusive (VC's don't have this problem since you almost always arrange it in advance)
i figure if my parents manage to use skype and email now, everybody will be using these newfangled systems in the future.

also discovered that FB has the voice facility too. a bit clumsy to get to it, but once there, the feature is easy to use. would be great if they replaced the stupid location button with the voice button.
Viber is a fantastic app and free. You can call everybody in your phone book as long as they are online as well. There is an option to select all sms / call replies go through Viber free instead of a regular call / sms. Also if you don't have a data plan or want to restrict viber use over it then there is a setting so that Viber is used only when connected to a wifi connection. Has helped me save a lot
