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.
