I have a few friends that have told me that since sending me pics over MMS, they get a "failure to send" message on their phones. This started yesterday, when i put my TMO sim in my new passport that just arrived yesterday. I even watched this happen from my wifes iPhone (also on TMO). Is there a setting on my phone that i need to look into to fix this? (note, it doesnt tell ME that i failed to recieve the MMS message, it gives them a failed message.)
