Did you read the article or are you merely responding to the title? The article begins by acknowledging triangulation and then moving on to the point of the article. The article is about commands built into the UMTS and LTE specs for requesting GPS from the device. Your comment seems to be about everything but the main point of the article.
Yes I saw that and also took it to mean the person didn't read the article. A text to your phone number? The article never mentions SMS. Heck I think the 2g/3g "feature" does not even require the phone to even have a SIM installed. This next sentence also seems to have been written without reading the article: "This can be turned off, since implementation."
I don't think it indicates their article reading either way and wouldn't personally wager a guess. They are just adding their own personal experience to the conversation.
I have read the article. It's speculative and not a reveal of anything new. All is ITU spec and came down from there. So there is quite some overlap in emergency service short code regions.
Another poster mentions 'ping', which is called pinprick for 112, which does work always, but requires authorization to be used. That I can confirm from experience.
