Your ISP can read any text message you send and view metadata logs of any phone calls you make. In lots of places (like Australia where I live) ISPs are actually required to keep logs of your messages and phone calls
Why would my Internet Service Provider have anything whatsoever to do with my dumb phone?
Yes, texts and calls aren’t hidden from your mobile phone provider, they never were. I agree it’s not great, and the government is likely spying on you as they have been for decades.
But alas, I don’t see a solution without using a non dumb phone and encrypted apps, which will require the internet and at that point you’ve not got a dumb phone any more.
My Nokia 3310 still works great. Sure, the government could spy on me, but I don’t discuss anything sensitive over the phone (traditionally one doesn’t, for this very reason, wiretaps and the like). It’s a tool for casually staying in touch and arranging to meet up _
To be fair to them, my parents grew up on a farm without electricity or running water. Unsurprising that they have less student debt than I do :3
