Need Suncom MMS settings for MDA

I have a Tmobile MDA that I am using on Suncom.

Everything works fine except MMS. Anyone here using an MDA or Kjam type phone on Suncom that has MMS working? I'd like to compare settings.

I have tried the settings on Suncom's web site.

I have achieved some success. I can now send MMS!

The secret was apparently entering the url for the gateway with no leading zeros.

Here is what I have entered 66.150.33.115

This now sends the MMS and I have a confirmation that it was received.

I can still not receive an MMS. I get the notification, but can not download the actual message.
