It’s malware — a virus. 1) No software will give update notices through text messages. 2) It doesn’t say what needs to get updated (so you can’t check it or try to do it directly). 3) The last line, lol: “It is safe and secure.” (“Oh, OK!”) I'd bet that “Trust us.” was in the first draft of this message, but they realized that was pushing it too far. DO NOT tap on this to install it. Block the number. Delete the messages.
