The baseband I believe is the stock Vz: 11A-M8974A-AAAANAZM-1.0.191007
I don't get any LTE with this, the best is HSPA+. Im in an LTE area and all the settings on the phone are to use LTE including the APN.
I was thinking of flashing a T Mobile modem but I have no idea what one. Could someone please point me in the right direction...
