There’s an LTE radio in here? Eh, it’s probably dormant. The radios are meant to be dormant. It’s not being marketed as a LTE phone, but it does have LTE.
AT&T and T-Mobile do not stop unlocked phones from accessing their networks. Verizon requires special authentication because of their CDMA network. Google could have released this unlocked with band 4 and 17 for use on AT&T (and later T-Mobile), but they chose not to for whatever reason.
