Is port forwarding possible on these SIMs?

Hi,

I recently purchased a Sixfab 4G/LTE Cellular Modem Kit for Raspberry Pi (EG25-G), which had an IoT SIM included. The whole setup connects to the internet fine, but I would like to connect to my Pi from another machine, in order to retrieve or put files onto the Pi & connected devices.

However, all attempts to ping my device from outside currently fail. From what I’ve read online, I need to enable port forwarding somehow on my device so that outside connections to my device are possible. Is this possible using Sixfab SIMs, and if so how do I enable it on my setup using atcom/minicom, etc.? Thanks!
