Thank you for this comment. I agree that the messages that I have documented so far are not direct threats to the user. However, unexpected or poorly understood pro-active behavior can create problems for a user, like in the wrongful death case in the original AT&T article.
As for SIMs from “troublesome” countries, and SIMs from specific people of interest, I also agree, and hope to continue this type on testing on these types of SIMs - as soon as I can get my hands on some.
