Yuilop is a tool that allows us to send traditional textmessages from our Android terminal to anyone else regardless of whether they have the application installed or access to the internet. Yes, you need an Internet connection via 3G or Wifi while sending messages, because this is how Yuilop works: The user 'supports' the advertisements in the application and in return, Yuilop covers the cost of the message, that will be sent directly to the mobile telephone of the person you want. In addition to this possibility to send text messages, Yuilop allows its users to be connected with each other in a way very similar to that of WhatsApp, and they can exchange multimedia files or engages in real time conversations. Not to mention the possibility of using Facebook chat to talk directly through it. Yuilop is a great application, and all that in exchange for just a little bit of advertising. which on the one hand, we are already more than accustomed to, it allows to send text messages without spending a single Euro. As long as you have an Internet Connection, of course.
