Post the output from AT!Gstatus?

When I built my WG3526 with a EM7565 I had a similar issue. The problem is likely not with your setup but with how AT&T is handling it. For me I was using a Red Pocket data sim and I was able to get Red Pocket to resolve the issue with how AT&T was allowing it to connect. Nothing I did on my end would fix the issue.

Would this help?
We can also set the modem to receive LTE only : at!selrat=06

Found it in this post : https://wirelessjoint.com/viewtopic.php?t=33#p107

So it fixed itself today after i reset it but i had to reset it because we had no internet
