Hello Friends,
I am very confused when I choose mobile network and global SIM card service providers.

They said LTE Cat-1 (the slower version of LTE) modem can connect to 4G mobile network.

So, how about Cat-M modem? Can it connect to an existing 4G mobile network? Please help me to clarify.

Pretty sure that that's not possible.
You definitely need a different SIM, and I think the towers are different too
