enter the following:
MMSC is

MMS Proxy is 66.209.11.33
MMS Port is 80
Keep in mind that Straight Talk has changed the complete APN set for some ATT SIM cards, namely the newer ones - and moving those SIMs to a 'tracfone' based APN. If data is not working with att.mvno, then your SIM was moved to the tracfone side...but if data works with att.mvno, then the above MMS settings should work.
I do have a new ATT SIM card (APN tfdata), but sadly this fix doesn't seem to work for me.
I'm somewhat resigned to the fact that it just doesn't work and ST doesn't particularly care. If you look at the Straighttalkwirelessforum.com, Howard Forums, XDA, etc., it seems as if ST has just wiped its hands of the issue.
Does anyone know if AIO lets people bring their own phones? I'm wondering if I would have any better luck with this issue if I got my service from an AT&T owned company.
