I keep getting this error. I went to AT&T store and the game me a new one but error keep happening. Could this just be a software issue?
Hope it's not a hardware issue. View attachment 2522954

To the best of my knowledge, AT&T provides a one year warranty against physical defects. S4 came out last May (?) so that shouldn't be an issue. I'd call back and talk to a different rep until you get them to offer a replacement. Having just gone through this about 3 weeks ago, I know it can be done.
The benefit of going through AT&T was that they sent out a replacement up front. I was never completely without a working phone.

Gave you a new what, sim card or phone? I had this same issue with my S4, and it was because I had failed to stop the OTA update while rooted. The issue went from intermittent to toatally disabling my phone in a period of about 1 month. After one full week of without phone service due to no sim card found (rebooting no longer worked), I had to unroot and allow the OTA update to MK2 FW. My sim card issue immediately went away.
Not saying that I doubt your results but... after getting the return authorization from at&t, I returned to stock (mdb) and allowed the phone to take the ota to mf3. I then checked for updates and went straight to mk2. Continued to get "sim not installed" error despite having the latest firmware.
Hope the op can replicate your results but it didn't work for me. Maybe the phone gods just hate me.
