SMS is completely insecure. Not only can it be passively sniffed along the way, not only can malicious actors reroute your number, not only can pretty much any employee at your telco access it, not only can pretty much any employee at your telco get tricked into rerouting it, but by default (and therefore for the vast majority of users), it'll show up while the phone is locked! It's equivalent to taping your key to your back door. Sure, someone has to go to your back door first to see it, but then they're in.
