I'm not sure about AT&T but the MMS service is simply added on to the sim card like GPRS or video (with a tick in a box) ... reason I know this that I work for Vodafone, my contract however is with O2 here in the UK... I'll be kicking *** if I find out MMS was never enabled on mine.... why not tell them you need to use MMS on another phone and just get it enabled that way?
Every new sim card sold by Vodafone comes with ability to add
voicemail.
VF e-mail
video conferencing
MMS
SMS
GPRS
So there is really no excuse... you will however need to find out the mms settings for your telecom however e.g
