my unlocked HTC Inspire will not send or receive MMS

I have an HTC Inspire, and I recently changed my service from AT&T to T-Mobile. I had to have the phone unlocked and then started T-Mobile service. After doing this, I can no longer send or receive Multimedia Messages. When trying to send, it gives the message, "Unable to send, failure", and when trying to receive MMS, it gives the option to download the image, but when I do, nothing happens and then it says, "unable to download, failure" HTC sent me some info but said that I need more APN Settings info.  I am at whits end! Thank you for the help!
