Is this router AT&T compatible?

We use an AT&T SIM and it works great. Their corporate office will try to tell you it isn’t compatible because of their “switch to 5G” but that’s just because they’d rather sell you their inferior whole home hotspot. I did have to change some settings to get it working correctly, but the dudes at my local AT&T were super helpful with getting me up and running.
