All the GSM bands on AT&T are supported, but not all LTE bands. LTE band 4 is supported, because that's same band as the 700mhz AWS spectrum Verizon bought (and is now advertising as "XLTE"). I wouldn't know how to tell or if you even can tell what band(s) of LTE that AT&T is using in your areas.
heres the bands used by ATT can u please tell me if its compatible with verizon ? Thanks
