This product was released in 2003. To be noticed that because of this, there is a good possibility that you won't be able to use it with your Windows phone. However, Microsoft SMS Sender has an error and will throw an error because it can't write your device's name in the corresponding registry file. To fix this, go to Start and type regedit and open the resulted service. In the new window that opened, go to My Computer > HKEY_ CURRENT_USER > Software > Microsoft > SMSSender, open the DeviceName file and input the name that appears in the program's GUI (Graphic User's Interface). This should fix the problem.
