Would using a USB modem with a sim card to access tor be much better than using my home internet? It would all obviously be paid for with cash and I was thinking I could change the sim card every now and then as well. (should I change the entire modem?) Would this be a waste of time since mobile phones (or this USB modem) could be tracked based on the cell towers, how accurate of a position are they able to track it to? Would driving to a new location each time I use it make it untraceable? I am also thinking about using a VPN to hopefully make it less obvious that I am using TOR.
I am basically trying to come up with an alternative to using public wifi networks as there are not many in my area and it would be really inconvenient to go find one all the time.
Just use Tor on your home internet connection. VPN/Mobile hotspot/Public wifi is what everyone used before Tor.
