Making a 4g proxy at home.

I'm trying to make a 4g network proxy at home. I want 100s of ips available at the same time. I have 3 rooted android phones. Could you lads instruct me a bit how do I go about it? Do I need 100s of devices with 100s of Sims to make 100 of ips available at the same time and what happends with Mac of the server? As I need the every ip to be unique to the device using it?

Also if that is not possible , can I connect multiple wifis at multiple VM'S with one usb adapter?

Sorry if my English is bad,it's my 3d language.
