Can I use a Zenfone 10 on AT&T?

Is there a way to use a Zenfone 10 on AT&T? I bought an unlocked, international version of the Zenfone 10, and can't get it to make calls. Apparently it is not on the list of AT&T approved phones. An AT&T support rep told me that the IMEI number doesn't show any history or even the make/model, only that I tried making calls with it a couple days ago using my usual AT&T sim card. She told me it was a "ghost phone." She also said it was showing up as a 3G phone, although it should go to 5G. (My area only supports 4G anyway.) Verizon couldn't make it work either. Is there a setting I can change to make it work?
