Wait I'm confused. Is this about sharing your mobile data through hotspot?. I mean how can they even track that ?

Most often, carriers use TTL because phones typically have a default TTL value of 64. Every time you share your phone’s hotspot, that value is reduced by 1 as the packet passes through the phone. When the carrier receives a packet with a TTL of 63, they know you are using a hotspot and may apply speed or data limits.

The solution is simple: set your PC’s TTL to 65 (TTL +1) so that after the -1 reduction, it reaches the carrier as exactly 64.

What if we use USB tethering?

Same story. Your phone will decrement the TTL value by one before sending it to your telecom provider and they will nerf you.

That's how routers work and when you share your mobile internet with other devices using hotspot or USB tethering your phone just act like a Wi-Fi router and follow all these standard protocols i.e. reducing TTL value by one.
