    I’ve reset the APN settings using the new settings above. I am able to send myself a picture message but when my husband sends me a picture message, it keeps flagging up “message not downloaded, retrying”. Not sure why this is. I am able to connect to my browser as well so I’m getting data. I have a straight talk sim that has been activated and I’m using it in an AT&T Go Phone. Any help will be greatly appreciated. I’ve contacted Straight Talk several times but they haven’t been able to help me.

      Launch “Settings” and tap on “General”
      Scroll to the bottom of General and tap on “Reset”
      Tap on “Erase All Content and Settings”
