This is the scariest one of all:

Looking down at my phone, there was no sign it had been hacked. I still had reception; the phone said I was still connected to the T-Mobile network. Nothing was unusual there. But the hacker had swiftly, stealthily, and largely effortlessly redirected my text messages to themselves. And all for just $16.

And:

I hadn’t been SIM swapped, where hackers trick or bribe telecom employees to port a target’s phone number to their own SIM card. Instead, the hacker used a service by a company called Sakari, which helps businesses do SMS marketing and mass messaging, to reroute my messages to him.

And:

Unlike SIM jacking, where a victim loses cell service entirely, my phone seemed normal. Except I never received the messages intended for me, but he did.

The fact that this is possible shows how unsafe, how vulnerable, our current security infrastructure truly is.
