Sometimes these hacks and cheats do not work on your smartphone, or your version is not suitable. I advise you to look at your phone's feature settings and see if they match the service you are trying to use. If it's okay, then the problem is with the software. It could also be low quality. In this case, I advise you to download another one, and better check information about it from friends or on forums, so as not to "install" bugs with a new service.
