To promote the new service of mobile broadband movistar, we decided that users try out the service even before hiring. 
This was the reason they were installed several mobile broadband devices and use them as wifi networks. 
The names of each network, formed together a message: 

Stop stealing Wifi 
Take it with you 
Movistar Mobile Broadband. 
Try it now. 
Here (open network) 
 
Thus users could test the service before purchase.
