Got the confirmation for my uConsole Kit RPI-CM4 Lite to come in later this week! Wondering about 4G additions

So as the title says, I got my notification that my uConsole is finally coming! I am beyond excited, as I had ordered this thing back in November 2023. I was a different person back then and with a whole year of learning Linux and more System admin stuff for my current job, I have more knowledge to throw at this thing now!

I was wondering if I could mod it to use 4G (I got the basic Wifi one) or if this kit would need me to buy a new one. Just curious as I have a few phone cards chilling in a cabinet.
