They absolutely do. I'm using the same family of devices and creating the accounts with different fingerprints (GPU, browser, Carriers, etc). I think what ultimately got me caught apart from too few subnets was the emails I was using to validate. Something so simple, yet effective. Do you have any recommendations? I'd rather not spend a lot of money on gmail accounts at the moment, for testing.
For perspective, I have my own 5G farm with each device having all three major carriers (Tmobile, Verizon, AT&T) and I have my own SDK that allows me to manipulate their chromium browsers, undetected of course. Bare metal IP/TCP mobile packets, real hardware, the works. Of course the only thing not airtight is emails :-/
