What is the difference between cellular data being used on my phone and cellular data being used on my notebook? Data is data.

    Great tip.

    Time to live (TTL) or hop limit is a mechanism which limits the lifespan or lifetime of data in a computer or network. TTL may be implemented as a counter or timestamp attached to or embedded in the data. Once the prescribed event count or timespan has elapsed, data is discarded or revalidated. In computer networking, TTL prevents a data packet from circulating indefinitely. In computing applications, TTL is commonly used to improve the performance and manage the caching of data.

    Hmm kinda makes sense

      I had a provider before that blocked tethering and hotspot, the solution there was also to increase TTL on the clients connecting to the phone by 1. The phone would lower it by 1 again, making it look like data originated from there.

      It’s possible to track the number of hops that a device on a network has, since TTL will be 8-bit numbers (and ususally start at 64, 128, etc.) if the TTL of a packet has 64 from the main device, the devices it’s sharing with will be 63 (and so on un the chain for N+1 hops). This may not be exactly how they do it since device fingerprinting would be way simpler, but it is a plausible way of tracking that a device is using a hotspot.
