Unable to connect to 4G with Lenovo Tab4

Hi, I am from Germany and visiting US right now. I bought a AT&T SIM card for my Lenovo Tab4 (Lenovo Tablet TB-8704X). I am traveling in Portland and all of Oregon but I never could connect to 4G. The tablet should be able to connect 4G, cause it is doing with my German T-Mobile SIM. The APN is set to AT&T Nextgenphone profile. What is the problem with AT&T SIM? Who can help?

Maybe the solution is as easy as updating the database with my IMEI as 4G device?

The tablet may not have hardware compatible with LTE services, or the IMEI will not register as an LTE device.   If it’s working on 3G, that is ATT’s 4G network.  Kinda of weird, att 3G is more like 3.75 speed.
