Why would you drive around? You can just put it in one place and spam. It doesn't change the network connectivity or the numbers or anything to drive, except perhaps running from law enforcement?
To avoid showing up on 2G/3G networks as a static congestion factor. SMS in 2G a can easily block calls if done intensively enough, since itβs part of the actual call signaling. We could tell when high-school classes ended by the sudden increase in SMS and decrease in call volumes in certain cells.
i don't recall exactly reason, quite a long time since then, but it has something to do with fake number detection and the amount of phone number we can reach.
