Why cant i send photos mms texts with my iphone 4 with straight talk as my carrier?

Is there any setting i need to change or something specific i need to do to allow the photos to go through text messages

the last couple of times i tried, it attempts but says there's an error. I have straight talk as my carrier. Can anyone help

Never used Straight Talk, only thing I can suggest is to click O on your phone and ask the operator to connect you to tech support and ask them.
