Bad sim then.
If you're phone doesnt recognize sim it's only 3 issues ( since you tried different roms and modems and didnt lose your imei so your efs isnt corrupted)
Either bad APN, bad Sim, or hardware issue.
Grab a sim from an at&t store.

Uh oh.
First I would odin back to stock. Then I would flash 4.3 bootloader via odin then flash a touchwiz 4.3 rom.
Also flash the at&t mk6 modem.

Has 4.3 bootloader and mk6 modem linked. Also has a link to what your apn should be so check the apn first.
Then flash the rom of your choice from development section

Do you have a baseband and IMEI? Check in you about phone. You may have to use Kies to recover back to 4.1.1
