A friend tried to send me a message with a voice attached the other day. I did not receive it. I contacted Optus in Australia and they went through my MMS settings with me. The strange thing was I could send an MMS, but not receive them. After much fiddling around I found that a title had to be put into the message or a message typed. I then received the MMS and was able to download the attached file. Has anyone else had this problem with the Galaxy or do you think it may be an Optus problem?
