Yuilop is a nice application Android which allows users of these phones to send SMS messages through the world and free. It is also, in addition, a good communication platform which allows you to put in contact users as on other networks.
Very useful particularly that the service it offers is free. Users of Yuilop can therefore send messages free and unlimited in more than 100 countries. It is also a good tool for instant messaging that allows its user to chatter together and can even integrate it into the network Facebook to find their friends on this social network. As on Twitter Yuilop allows you to compose messages which should not exceed 160 characters but the fact of having the ability to send unlimited messages we can write as much as you want. The small concern that a few users will meet is that of the language because the application is in German.
