I have the same problem as Tracy, but my carrier is T-Mobile and I don't have any boost app on my phone. I receive pics as a text message from anyone, but unable to send. I've tried attaching the pic directly from the Paper clip Icon, and by going directly to pics to select a pic first and then select 'send' via text msg. it just keeps buffering, circle turning, for sometimes a minute or more, then error message simply says, unable to send. I've tried selecting from the Gallery ( which I think is either a droid app, or a Samsung app that was already available on the phone, and I've tried selecting and sending from Google backup icon called Photos. neither works. I try to re-size pics to be smaller, try to send them as a slide, and nothing works. Can someone explain what is wrong and how to correct this? Thank you.
