W810i MMS Failure

Hi everyone, I just unlocked my phone and now I can't get MMS or internet, I get this message "Download Failed. Internet Profile Error. Check your internet settings." I've been searching the forums and some people can use SE's website to send them the settings but I'm on ATT and they don't have the settings for w810i. Can anyone help me out?

You Mean SE Dont Have Settings For AT&T. Ask AT&T For Settings.

Sometimes those AT&T Reps don't like to help people with unlock phones that cannot connect to the internet or send text messages.
