None of the MiWay official advertised numbers work, ***and ***, get number does not exist when dialing on my cellphone. The APP does not work, the only thin on the APP that does seem to work displays a page listing the telephone numbers that do not work. the only thing that seems to work sort off is the WhatsApp chatfacility where you get multiple people joining the conversation but very little feedbac and having to repeat yourself several times. Overall a very frustrating experience.
