Verizon SIM pulled from working Pepwave Max BR1 placed in the RBM11G shows up and connects fine. The problem is that its appears to be getting a /32 from the carrier.
The Pepwave gets a /30 from Verizon. Both are using the VZWINTERNET APN.

When using a /32 the default gw is just pointed to the lte1 interface and that does not seem to work. No return traffic whatsoever.

[admin@MikroTik] > /interface lte at-chat lte1 input="AT+CGCONTRDP"
output: +CGCONTRDP: 1,5,VZWINTERNET,100.112.44.84,,198.224.167.135,198.224.166.135

Above show its gets an address but no default gateway is specified and it does have two DNS servers but only the first is added to the dynamic DNS entry on the Mikrotik.

Now when I put it in passthrough mode the device connected to the RBM11G will get a /30.

So why is that?

Tried, Bugfix, Current, RC and applicable firmware updates.
