I ask cause I tried it and MMS didn't work in GO SMS Pro.
The nexus 4 will only support band 4 aws LTE and that band is only a small part of AT&T spectrum so you can probably figure it out...
I'm currently using one in my N4 so yes it does, but obviously the LTE doesn't work.

Have you tried dialing *#*#4636#*#* apparently shows that it does support Lte who knows
I have my LTE SIM card in my n4 from my gs3. Works fine.
AT&T moved SIM card from my S3 to my Nexus 4 and all is working well.
