I was having the same issue of not being able to send or receive picture messages. I spent over an hour in a chat with an ATT&T rep and ended up telling me to do a master reset or call Samsung. After reading this, I logged into my account online and unlinked the Unlimited Family Messaging and added it back myself and fixed the issue!!! Thanks!!!
Hah! Couple of you were right, indeed!
While I was on hold, and reading MrTony's post, I remembered that when I upgraded my main line (3GS) to Captivate, they had to remove Family Messaging Unlimited to do the upgrade, and then put it back.
Guess what happened?
Yeah - he fixed it by re-adding Family Messaging Unlimited, and MMS is working here, send and receive.
Tks for posting info, folks - let's keep this going on all threads, and most people can call AT&T most times knowing what their issue is beforehand!!!!
Now to get more than 1-2 bars in my home...
And no, it ain't the Cappy - EVERY PHONE we've had here the past 10 years has exhibited the same issues. Guy on the phone did say a new 3G tower was coming up just East of my house on August 27th, so let's see if that helps some!
