différence entre whatsapp , viber, gtalk ?

[Laddy]

Bonjour

je voudrai savoir quelles différentes y a t il entre ces différents logiciels ?

car pour moi ce sont des messageries instantanées, est ce que l'un d'entre eux se base sur les numéros de téléphone directement ?

J'ai lu que les personnes devaient avoir le meme logiciel pour communiquer, je ne vois pas le rapport avec le sms , qui est utilisé par nos opérateurs.

Merci à ceux qui m'éclaireront sur ce sujet.

Bonne journée

Salut,

Ceci est un représentant officiel de Viber Media.

Je m'excuse, mon français n'est pas si bon, si je vais écrire en anglais:

We wouldn't want to compare Viber to any other specific app, but I can list few of Viber's biggest advantages:

* Viber's interface is very easy to use - it looks completely similar to your device's basic application, and this makes a huge difference for most users in the world. Simple elegance is what works.

* Viber does not require login/password in order to log in, unlike the great majority of VoIP applications today, but instead it uses the user's original cellular phone number. This makes the registration process very quick, and helps users find other friends who have Viber very easily (and automatically). This way more and more friends recommend each other to install Viber, and have free calls and texts.

* Finally, Viber doesn't have to be open when receiving a call, thanks to Viber's support of Push Notifications feature in iPhone or C2DM in Android OS. This means that Viber saves battery, and that users are always available to receive Viber's free calls.

Lastly - we believe that the service itself that Viber provides, in terms of call quality, functionality, etc. is simply reliable, and users appreciate that and choose to install and use it on a daily basis all around the world (it's popular for both domestic and international).

If you have any question about Viber - please feel free to ask.

Merci,

the Viber Team.
