Probably local/system services on the app when the SIM is activated (like it’s with sim locked phones)
Comment on I have unlimited cellular data on my phone but not if I use it as a hotspot.

How do they even know if you use your data as a hotspot? That’s just ridiculous!

Nope, it’s either inspecting the TTL of packets coming from your phone (unless you have a VERY custom setup, the TTL from devices other than your phone will be very different), or it’s deep packet inspection. I tried to trick t-mobile last year into giving me home internet on a phone sim, so I did a whack ton of research.

Did you find a way to avoid detection?

On US Mobile (Verizon) using a VPN on my phone when tethering seems to bypass detection. At least the meter on the dashboard says I’ve used 0gb hotspot.

Monitoring DNS requests to their own servers.

They look at the TTL of the incoming packets. This can be modified in the windows registry.

Makes you wonder what else they know about what you’re doing online.

He wrote that 5 years ago (admittedly I have yet to read it), so who knows what they’ve been able to do since then than he hadn’t even thought of.

It’s still very relevant and one of the most mind blowing things I’ve ever read
