to some level it does, but this is not like the Verizon hardware where
you have dedicated chips for CDMA and LTE, this seems to have one chip
that can operate in GSM/UMTS and LTE.

So from a pure AT command level interface all EPS commands are there,
but I have not yet been able to make them work properly. In theory this
hardware should also support IPV4V6 dual stack contexts, but it is still
behaving funny when trying.
