*app, not “up”
When I send people texts, they might be Apple users or any other various phones and texting apps, are any of their texting apps such that it notifies them when a message has been seen or read?
I don’t get “seen” or “read” information on my end. Do they?
Lol, even better.
Though shouting into a room isn’t too far off - it’s sent via plain text, so anyone could on the IP network can read it, if they wanted to (the cell part is moderately more secure, though susceptible to man-in-the-middle, such as Stingrays).
