Yeah, that's what I thought.  But it doesn't see VZW even though I
should be getting about -65dBm LTE here.

Ah, thanks for the info.  Though I'm probably ditching the VZW
subscription soon, and I also have T-Mobile which pretty much shares
bands with AT&T.  So not sure how much I'll end up pursuing this; it was
just easier to grab the VZW SIM from my laptop than take my phone out of
the case, find a PIN to eject the SIM tray, etc :)
