Orbi LBR20 on Nomad Internet with AT&T SIM

Rural dweller here. Considering purchasing service from Nomad Internet (www.nomadinternet.com). I recently purchased the Orbi LBR20 LTE Router. Looking at Blue Plan (AT&T SIM). Has anyone had first hand expereince with this set-up? My concern is the issue I have heard about where a MEID mismatch causes frequent disconnections...

I am currently testing using my unlimited Verizon phone SIM and (as expected) I do get frequent disconnects as others have reported. Works well when connected. We have decent AT&T service available as well.

Thanks!
