I believe that the standard commands work OK on these, eg AT*99*1# or
whatever it is to select the right PDP context.  But you'll certainly
not get anywhere near LTE speeds with PPP.  The best thing to do is use
the NDISDUP commands on the right AT port and then use the
pseudo-ethernet interface that the modem exports along with DHCP, or
statically configured with the AT^DHCP command (or whatever it is) that
the modem provides.  I forget all the details of the Huawei NDISDUP
implementation but Google knows...
