Problem sending ringtones to my phone !

Hi !
How is everyone ? I am new with Verizon,I have Samsung A870 .I have been sending MP3 ringtones using the PIX message as an attachment,also tried with some ringtone software ! The only option I have is to save the ringtone in My Sound Folder ! Is there anyway I can save it as ringtone ? Any help would be appreciated ! Is this possible or impossible ? Thanks Alot ! Looking foward to hear from someone ! Have a nice day !

On that phone, you have to save the file as a Sound. Then you simply navigate to that sound and "set as" Ringtone or Ringer ID.
