Question hacking, and pentesting, and simulation.

Hi!

is it possible to do pen testing and simulations and anything using a 4G connection with unlimited data SIM?
soon i buy a computer what do you recommend 1 cpu or 2 cpu or 4 sockets cpu? AMD or INTEL?. eventually I buy used computers and used servers.
if you can do all this with 4G unlimited data connection thank you I can't make a fiber connection because it costs too much and I don't want a landline phone.
Thank you and I'm waiting for answers.
