Yeah this can still happen if your phone so happens to connect to an old 2G GSM tower. They’ve been phasing them out for years, but there’s still plenty of them in lesser-populated areas because it’s reliable and you don’t need to have as many towers to get a good signal.
I still sometimes hear this if my phone drops fron 5G and I am around a really cheap speaker.
