US 4G LTE carrier bands: the BIG picture That would be the 1900MHz band 2 (B2) for AT&T; the 1900MHz B2 together with 1700MHz AWS bands B4 and B66 for Verizon ; and pretty much the same combination of B2, B4 and B66 for T-Mobile. Those bands make the backbone of 4G LTE network coverage especially for urban areas.
