Fun Fact: Some carrier throttling works by throttling packets with an unexpected TTL. Android has a default TTL of 64.

You most certainly shouldn't set the default TTL of a tethered device to 65, because then your carrier may fail apply proper limits to that traffic.

Here in Asia, if my data plan is reached quota, I'll be charged by bandwidth: $x/MB and it's much more expensive than the normal data plans. So I still have full throughput but pay significantly more for it.
