4G Private proxies setup at home

Hello to all,

It took me a few days and I manage to set up a proxy server at home with 5 phones with 4G.
so actually every phone has proxy user/pass and I can set it as a proxy to jarvee.
Working amazing - ping is 700. and running super fast

Now. as I am new on this. I will try only 1 IG + 1 FB account on 1 phone.
What do you think? It’s a private 4G proxy.
Should I start from fresh account or aged. this is my only concern

How did you manage to solve the having same ip from each phone ? was it usb thetering or hotspot ?
