A fix has surfaced for those having trouble sending or receiving MMS messages on the Dell Venue Pro using the AT&T Network. As one would suspect, it's a settings issue but you first have to pull up the diagnostic screen.
While we've haven't heard of any horror stories in tweaking these settings, please keep in mind that you proceed at your own risk. Here are the steps.
- From your Dell Venue Pro, bring up the dial pad and enter ##634# to bring up the diagnostic screen.
- Tap on MMS Settings.
- Scroll to the MMS Settings section.
- The settings should be Name: ATT MMS (all caps), APN: wap.cingular, MMSC: http://mmsc.cingular.com, MMS Proxy: wireless.cingular.com, MMS Port: 80, Username: (leave blank), Password: (leave blank).
- Scroll up to the Auth Type, tap CHAP, and then Apply.
You should then get a "Success, Setting is Done!" message. Tap OK, then tap HOME and you should now be able to send and receive MMS messages from your Dell Venue Pro. There have been some reports that you need to restart the phone to get the settings changes to take hold.
