The Motorola G100 is easily rooted. It works with that whitelisting carrier (AT&T). Also works on other GSM networks (T-Mobile, etc).

It's dual physical SIM, the 2nd SIM slot doubles as microSD. Has 3.5 jack, 802.11 AC and does 5G. The rest of the specs are pretty okay.

Worst thing is side button dedicated to Google, which can be 'fixed' after rooting.
