User Network Functionality with 5G Development Kit / 5G Hats

I am attempting to connect through my SixFab 5G hat to pull unsolicited (not scammer based) calls, texts, file transfers from the host 5G network onto the Raspberry Pi. I have the network assigned IP address for using the SIM card, and the Raspberry Pi has a self assigned IP address to the USB port. I need a process to receive information strait to the Pi 's IP address as it arrives. Likewise, I need to forward files strait from the Pi’s IP assignment using forwarding protocols. I am worried that the Hat itself has an IP address that I cannot forward through. If this is so, can someone provide the example code required on the hat to allow this configuration?

If the product cannot support this, then I want to know.
