Send a text, and it pops up just like a normal text on their cellular device. This is extremely useful when working with Clients abroad and you need quick feed back. Furthermore, it allows you to text any number for free as long as they also have the Viber app. Viber is extremely versatile in that it allows you to make free VOIP calls with HD sound quality. It's my go to international communication app. I have had Skype and FaceTime fail me while abroad, but Viber has not. Comments: My overall experience with Viber is the app is RELIABLE.
