I recently switched to a new mobile data plan that lets me have unlimited mobile data but only 3GB of hotspot. Since I don't have Wi-Fi access at home and public Wi-Fi is quite a distance away, I decided to adjust the TTL (Time-To-Live) on my laptop to try and save on my hotspot data. I followed some instructions to change the TTL value in the Windows Registry from 128 to 65. I rebooted my computer afterward, and while I can confirm the TTL value is set to 65 when I check the ping in Command Prompt, my hotspot data limit is still decreasing. Can someone help me understand why this isn't working like it did before?

Just a tip: TTL is basically a header that tells your network how many hops a packet can make before being discarded. If changing it worked before, it's possible that your new provider is using a different method that doesn't rely on TTL. You might want to check if there's any specific info on what your carrier does to monitor hotspot usage.
Since you changed your plan, this method may not work with your new provider. Carriers have various ways to track usage, and TTL is just one method among many. They could be using different strategies now to differentiate between hotspot and mobile data usage.
Changing the TTL won't actually reduce the data you're using on your computer. It's more about how often your data packets are allowed to hop between routers. To save data, you might want to lower the resolution on video sites like YouTube, avoid downloading large files, and consider using DNS-based ad blockers to prevent ads from consuming data. Also, make sure to uninstall any apps you're not using but still get updates because they can eat up your data too.
I've been using a tool called PDANet for years, which helps me bypass data limits. It usually costs a little, but it might be worth it if you're looking for a solution. Just something to think about!
Exactly! The TTL change usually affects routing but doesn't necessarily stop your carrier from tracking data usage through other means. It’s a good idea to look into how your new provider handles these kinds of changes.
